/*
* NAME
* semop01.c
*
* DESCRIPTION
* semop01 - test that semop() basic functionality is correct
*
* ALGORITHM
* create a semaphore set and initialize some values
* loop if that option was specified
* call semop() to set values for the primitive semaphores
* check the return code
* if failure, issue a FAIL message.
* otherwise,
* if doing functionality testing
* get the semaphore values and compare with expected values
* if correct,
* issue a PASS message
* otherwise
* issue a FAIL message
* else issue a PASS message
* call cleanup
*
* USAGE: <for command-line>
* semop01 [-c n] [-f] [-i n] [-I x] [-P x] [-t]
* where, -c n : Run n copies concurrently.
* -f : Turn off functionality Testing.
* -i n : Execute test n times.
* -I x : Execute test for x seconds.
* -P x : Pause for x seconds between iterations.
* -t : Turn on syscall timing.
*
* HISTORY
* 03/2001 - Written by Wayne Boyer
* 17/01/02 - Modified. Manoj Iyer, IBM Austin. TX. manjo@austin.ibm.com
* 4th argument to semctl() system call was modified according
* to man pages.
* In my opinion The test should not even have compiled but
* it was working due to some mysterious reason.
*
* RESTRICTIONS
* none
