.Sh DESCRIPTION
|
||||
The string
|
||||
functions manipulate strings terminated by a
|
||||
nul byte.
|
||||
.Pp
|
||||
See the specific manual pages for more information.
|
||||
For manipulating variable length generic objects as byte
|
||||
strings (without the nul byte check), see
|
||||
.Xr bstring 3 .
|
||||
.Pp
|
||||
Except as noted in their specific manual pages,
|
||||
the string functions do not test the destination
|
||||
for size limitations.
