+.Sh NAME
+.Nm pthread_setaffinity_np ,
+.Nm pthread_getaffinity_np
+.Nd affinity of threads
+.Sh LIBRARY
+.Lb libpthread
+.Sh SYNOPSIS
+.In pthread.h
+.In sched.h
+.Ft int
+.Fn pthread_setaffinity_np "pthread_t thread" "size_t size" "cpuset_t *set"
+.Ft int
+.Fn pthread_getaffinity_np "pthread_t thread" "size_t size" "cpuset_t *set"
+.Sh DESCRIPTION
+Thread affinity allows to run the thread on specified CPU or CPUs only.
+.Pp
+The
+.Fn pthread_setaffinity_np
+function sets the affinity mask
+.Fa set
+for
+.Fa thread .
+At least one valid CPU must be set in the mask.
+.Pp
+The
+.Fn pthread_getaffinity_np
+function gets the affinity mask of
+.Fa thread
+into
+.Fa set .
+Note that
+.Fa set
+must be created and initialized using the
+.Xr cpuset 3
+functions.
+.Sh IMPLEMENTATION NOTES
+Setting CPU
+.Nm
+requires super-user privileges.
+Ordinary users can be allowed to control CPU affinity
+of their threads via the
+.Pa security.models.extensions.user_set_cpu_affinity
+.Xr sysctl 7 .
+See
+.Xr secmodel_extensions 9 .
+.Pp
+Portable applications should not use the
+.Fn pthread_setaffinity_np
+and
+.Fn pthread_getaffinity_np
+functions.
+.Sh RETURN VALUES
+The
+.Fn pthread_setaffinity_np
+and
+.Fn pthread_getaffinity_np
+functions return 0 on success.
+Otherwise, an error number is returned to indicate the error.
+.Sh EXAMPLES
+An example of code fragment, which sets the affinity for the current
+thread to the CPU whose ID is 0:
+.Bd -literal
+	cpuset_t *cset;
+	pthread_t pth;
+	cpuid_t ci;
+
+	cset = cpuset_create();
+	if (cset == NULL) {
+		err(EXIT_FAILURE, "cpuset_create");
+	}
+	ci = 0;
+	cpuset_set(ci, cset);
+
+	pth = pthread_self();
+	error = pthread_setaffinity_np(pth, cpuset_size(cset), cset);
+	if (error) {
+		...
+	}
+	cpuset_destroy(cset);
+.Ed
+.Sh COMPATIBILITY
+Both functions are non-standard extensions.
+.Sh ERRORS
+Both functions may fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The specified
+.Fa set
+was invalid.
+.It Bq Er EPERM
+The calling process lacks the appropriate privileges to perform
+the operation.
+.It Bq Er ESRCH
+No thread could be found corresponding to the one specified by
+.Fa thread .
+.El
+.Sh NOTES
+There is an alternative processor sets interface, see
+.Xr pset 3 .
+However, thread affinity and processor sets are mutually exclusive,
+hence mixing of these interfaces is prohibited.
+.Sh SEE ALSO

+.Sh NAME
+.Nm pthread
+.Nd POSIX Threads Library
+.Sh LIBRARY
+.Lb libpthread
+.Sh SYNOPSIS
+.In pthread.h
+.Pp
+.Nm cc
+.Op Ar flags
+.Ar files
+.Fl lpthread
+.Op Ar libraries
+.Sh DESCRIPTION
+The
+.Nm
+library provides an implementation of the standard
+.Tn POSIX
+threads library.
+.Pp
+The
+.Nx
+implementation is based on 1:1 thread model, therefore each
+.Nm
+has a kernel thread, called a light-weight process (LWP).
+.Pp
+Note that the system private thread interfaces upon which the
+.Nm
+library is built are subject to change without notice.
+In order to remain compatible with future
+.Nx
+releases, programs must be linked against the dynamic version of the
+thread library.
+Statically linked programs using the
+.Tn POSIX
+threads framework may not work when run on a future version of the system.
+.Sh FUNCTIONS
+The following functions comprise the core of the
+.Nm
+library:
+.Bl -column -offset indent "pthread_barrier_destroy(3)" "XXX"
+.It Sy Function Ta Sy Description
+.It Xr pthread_attr 3 Ta thread attribute operations
+.It Xr pthread_barrier_destroy 3 Ta destroy a barrier
+.It Xr pthread_barrier_init 3 Ta create a barrier
+.It Xr pthread_barrier_wait 3 Ta wait for a barrier
+.It Xr pthread_barrierattr 3 Ta barrier attribute operations
+.It Xr pthread_cancel 3 Ta cancel the execution of a thread
+.It Xr pthread_cleanup_push 3 Ta add or remove cleanup functions
+.It Xr pthread_cond_broadcast 3 Ta unblock one or more threads
+.It Xr pthread_cond_destroy 3 Ta destroy a condition variable
+.It Xr pthread_cond_init 3 Ta create a condition variable
+.It Xr pthread_cond_wait 3 Ta wait for a condition variable
+.It Xr pthread_condattr 3 Ta condition attribute operations
+.It Xr pthread_create 3 Ta create a new thread
+.It Xr pthread_detach 3 Ta detach a thread
+.It Xr pthread_equal 3 Ta compare thread identifiers
+.It Xr pthread_exit 3 Ta terminate the calling thread
+.It Xr pthread_getspecific 3 Ta get a thread-specific data value
+.It Xr pthread_join 3 Ta wait for thread termination
+.It Xr pthread_key_create 3 Ta thread-specific data key creation
+.It Xr pthread_key_delete 3 Ta delete a thread-specific data key
+.It Xr pthread_kill 3 Ta send a signal to a specific thread
+.It Xr pthread_mutex_destroy 3 Ta free a mutex
+.It Xr pthread_mutex_init 3 Ta create a mutex
+.It Xr pthread_mutex_lock 3 Ta acquire a lock on a mutex
+.It Xr pthread_mutex_unlock 3 Ta unlock a mutex
+.It Xr pthread_mutexattr 3 Ta mutex attribute operations

+.It Xr pthread_spin_lock 3 Ta acquire a spin lock
+.It Xr pthread_spin_unlock 3 Ta release a spin lock
+.It Xr pthread_testcancel 3 Ta set cancelability state
+.El
+.Sh ENVIRONMENT
+The following environment variables affect the behavior of the library:
+.Bl -tag -width "XXX"
+.It Ev PTHREAD_DIAGASSERT
+Possible values are any combinations of:
+.Pp
+.Bl -tag -width "X " -offset 1n -compact
+.It Em A
+Report errors to application by error return, but do not abort.
+.It Em a
+Abort on errors, creating a core dump for further debugging.
+.It Em E
+Do not log errors to stdout.
+.It Em e
+Log errors to stdout.
+.It Em L
+Do not log errors via
+.Xr syslogd 8 .
+.It Em l
+Log errors via
+.Xr syslogd 8 .
+.El
+.Pp
+If not set in the environment, the
+.Nm
+library behaves as if
+.Em AEL
+has been specified.
+.It Ev PTHREAD_STACKSIZE
+Integer value giving the stack size in kilobytes.
+This allows to set a smaller stack size than the default stack size.
+The default stack size is the current limit on the stack size as
+set with the shell's command to change limits
+.Ic ( limit
+for
+.Xr csh 1 ,
+or
+.Ic ulimit
+for
+.Xr sh 1 ) .
+.El
+.Sh SEE ALSO

+.%D 1997
+.%I Addison-Wesley
+.Re
+.Sh STANDARDS
+The
+.Nm
+library conforms to
+.St -p1003.1-2001 .
+.Sh CAVEATS
+Due to limitations in the current pthread implementation,
+.Xr makecontext 3
+and
+.Xr sigaltstack 2
+should not be used in programs which link against the
+.Nm
+library (whether threads are used or not).

+.Os
+.Sh NAME
+.Nm pthread_attr_init ,
+.Nm pthread_attr_destroy
+.Nd thread attribute operations
+.Sh LIBRARY
+.Lb libpthread
+.Sh SYNOPSIS
+.In pthread.h
+.Ft int
+.Fn pthread_attr_init "pthread_attr_t *attr"
+.Ft int
+.Fn pthread_attr_destroy "pthread_attr_t *attr"
+.Sh DESCRIPTION
+Thread attributes are used to specify parameters to
+.Fn pthread_create .
+One attribute object can be used in multiple calls to
+.Fn pthread_create ,
+with or without modifications between the calls.
+The
+.Vt pthread_attr_t
+type is an opaque representation of the thread attributes;
+any access to the object other than via the described
+.Fn pthread_attr_*
+functions may result in undefined behavior.
+.Pp
+The
+.Fn pthread_attr_init
+function initializes
+.Fa attr
+with the default thread attributes used in the implementation.
+Depending on the implementation, undefined behavior may follow
+if an uninitialized thread attribute object is used with some of
+the thread attribute functions.
+It is therefore a good practice to always use
+.Fn pthread_attr_init ,
+even if this might be unnecessary.
+Undefined behavior may also follow if an already initialized
+.Fa attr
+is used with
+.Fn pthread_attr_init .
+.Pp
+When the attribute object is no longer needed,
+it should be destroyed by using
+.Fn pthread_attr_destroy .
+The function has no effect on threads that
+were created by using a given attribute object.
+A destroyed
+.Fa attr
+can be reinitialized using
+.Fn pthread_attr_init ,
+but all other actions with the destroyed object are unspecified.
+.Pp
+The following standard thread attribute functions are available:
+.Bl -column -offset indent "pthread_attr_getinheritsched " "XXX"
+.It Sy Function Ta Sy Description
+.It Xr pthread_attr_getdetachstate 3 Ta thread detach state
+.It Xr pthread_attr_getguardsize 3 Ta thread guard size
+.It Xr pthread_attr_getinheritsched 3 Ta inherit scheduler attribute
+.It Xr pthread_attr_getschedparam 3 Ta thread scheduling parameter
+.It Xr pthread_attr_getschedpolicy 3 Ta thread scheduling policy
+.It Xr pthread_attr_getscope 3 Ta thread contention scope
+.It Xr pthread_attr_getstack 3 Ta thread stack
+.It Xr pthread_attr_getstacksize 3 Ta thread stack size
+.It Xr pthread_attr_getstackaddr 3 Ta thread stack address
+.El
+.Pp
+Each listed
+.Fn pthread_attr_get*
+function has a
+.Fn pthread_attr_set*
+counterpart.
+In addition, the following
+.Nx
+specific extensions are available:
+.Bl -column -offset indent "pthread_attr_getinheritsched " "XXX"
+.It Sy Function Ta Sy Description
+.It Xr pthread_attr_get_np 3 Ta attributes of a running thread
+.It Xr pthread_attr_getname_np 3 Ta descriptive name of an attribute
+.El
+.Sh RETURN VALUES
+If successful, these functions return 0.
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+No errors are defined for
+.Fn pthread_attr_init
+and
+.Fn pthread_attr_destroy .
+.Sh SEE ALSO
+.Xr pthread_create 3 ,
+.Xr pthread_join 3
+.Sh STANDARDS
+Both
+.Fn pthread_attr_init
+and
+.Fn pthread_attr_destroy
+conform to
+.St -p1003.1-2001 .

+functions can be used to retrieve attributes of a running
+.Fa thread .
+The result is stored to
+.Fa attr .
+.Pp
+For

+.Fa attr
+should be initialized prior to the call by using

+.Ft int
+.Fn pthread_attr_setguardsize "pthread_attr_t *attr" "size_t guardsize"
+.Sh DESCRIPTION
+The
+.Fn pthread_attr_getguardsize
+and
+.Fn pthread_attr_setguardsize
+functions get and set
+.Fa guardsize
+in the
+.Fa attr
+object.
+If
+.Fa guardsize
+is larger than 0, the system reserves
+an additional region of guarded memory of at least
+.Fa guardsize
+bytes at the end of the thread's stack for each new thread created by using
+.Fa attr .
+.Pp
+The guarded area is understood to be pages of memory
+that are protected from read and write access.
+While the guarded area should be rounded by the system page size,
+the actual default size is implementation-defined.
+In
+.Nx
+the default
+.Fa guardsize
+is
+.Dv _SC_PAGESIZE ,
+the system page size.
+.Pp
+The rationale behind
+.Fa guardsize
+is two-fold:
+.Bl -enum -offset 2n
+.It
+On the one hand, it provides protection against overflow of the stack pointer.
+If there is a guard area and a thread overflows its
+stack pointer into this extra memory area, it should receive a
+.Dv SIGSEGV
+signal or experience other comparable fatal error condition.
+Note that if a thread allocates large data structures on stack,
+it may be necessary to raise the default
+.Fa guardsize
+in order to detect stack overflows.
+.It
+On the other hand, the overflow protection may waste system resources
+if an application that creates a large number of threads knows that it
+will never overflow the stack.
+In this case it is possible to set
+.Fa guardsize
+to 0.
+.El
+.Pp
+If
+.Xr pthread_attr_setstack 3
+or
+.Xr pthread_attr_setstackaddr 3
+is used to set the stack address attribute in
+.Fa attr ,
+the guard size attribute is ignored and no guard area will be allocated;
+it is the responsibility of the application to handle the overflow conditions.
+.Sh RETURN VALUES
+If successful, both functions return 0.
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+No errors are defined for
+.Fn pthread_attr_getguardsize .

+.Sh DESCRIPTION
+The
+.Fn pthread_attr_getstack
+and
+.Fn pthread_attr_setstack
+functions get and set, respectively, the thread stack attributes
+.Fa stackaddr
+and
+.Fa stacksize
+in the
+.Fa attr
+object.
+The remaining four functions behave similarly,
+but instead of getting or setting both
+.Fa stackaddr
+and
+.Fa stacksize ,
+these get and set the values individually.
+.Pp
+The
+.Fa stacksize
+parameter is defined to be the minimum stack size (in bytes)
+allocated for the thread's stack during the creation of the thread.
+The
+.Fa stackaddr
+attribute specifies the location of storage to be used for the thread's stack.
+All pages within the stack described by
+.Fa stackaddr
+and
+.Fa stacksize
+should be both readable and writable by the thread.
+.Pp
+The behavior is undefined in all functions if the
+.Fa attr
+parameter does not refer to an attribute object initialized by using
+.Xr pthread_attr_init 3
+prior to the call.
+In addition, undefined behavior may follow if the
+.Fn pthread_attr_getstack
+function is called before the
+.Fa stackaddr
+attribute has been set.
+.Ss Rationale
+The rationale behind these functions is to address cases where an application
+may be used in an environment where the stack of a thread must be placed to
+some particular region of memory.
+For the majority of applications, this is seldom necessary,
+and the use of these functions should be generally avoided.
+At least few potential caveats can be mentioned.
+.Bl -bullet -offset 2n
+.It
+There is a certain degree of ambiguity in the
+.Tn POSIX
+standard with respect to thread stack.
+.It
+The exact behavior of the functions may vary
+both across machines and operating systems.
+In particular, the address specified by
+.Fa stackaddr
+should be suitably aligned.
+The system page size, as specified by
+.Xr sysconf 3 ,
+and the use of
+.Xr posix_memalign 3
+may guarantee some degree of portability.
+Also
+.Xr mmap 2
+provides means for alignment.
+.It
+If the application modifies the stack address, it claims also
+the responsibility of allocating the stack area and guarding it against
+possible stack overflow.
+No default guard area will be allocated (see
+.Xr pthread_attr_getguardsize 3 ) .
+It may be necessary to manually use
+.Xr mprotect 2
+in order to define a guard area at the end of the allocated stack.
+.It
+Moreover, if
+.Fa attr
+is used to create multiple threads, the stack address must be changed
+by the application between successive calls to
+.Xr pthread_create 3 .
+.El
+.Sh RETURN VALUES
+If successful, these functions return 0.
+Otherwise, an error number is returned to indicate the error.
+.Sh ERRORS
+No errors are defined for the three functions that obtain the stack values.
+The three functions that set the stack values may fail if:
+.Bl -tag -width Er
+.It Bq Er ENOMEM
+There was insufficient memory to complete the operation.
+.El
+.Pp
+The
+.Fn pthread_attr_setstacksize
+function may additionally fail if:
+.Bl -tag -width Er
+.It Bq Er EINVAL
+The specified
+.Fa stacksize
+is less than
+.Dv PTHREAD_STACK_MIN
+or exceeds some system-imposed limit.
+.El
+.Sh SEE ALSO
+.Xr pthread_attr 3 ,
+.Xr pthread_attr_setguardsize 3
+.Sh STANDARDS
+All described functions conform to
+.St -p1003.1-2001 .
+Note that
+.Fn pthread_attr_getstackaddr
+and
+.Fn pthread_attr_setstackaddr
+were however removed from the specification in the
+.St -p1003.1-2008
+revision.

+.Ft int
+.Fn pthread_attr_setcreatesuspend_np "pthread_attr_t attr"
+.Sh DESCRIPTION
+The
+.Fn pthread_attr_setcreatesuspend_np
+function sets the
+.Ar attr
+argument, so that if this
+.Ar attr
+is used in a
+.Xr pthread_create 3
+call, then the thread created will not run, but it will remain blocked
+in the suspended queue, until
+.Xr pthread_resume_np 3
+is called on it.
+.Sh RETURN VALUES
+The
+.Fn pthread_attr_setcreatesuspend_np
+function always returns 0.
+.Sh COMPATIBILITY
+The function is a non-standard extension.
+.Sh ERRORS
+No errors are defined.
