/*
* Test Name: getresuid01
*
* Test Description:
* Verify that getresuid() will be successful to get the real, effective
* and saved user id of the calling process.
*
* Expected Result:
* getresuid() should return with 0 value and the real/effective/saved
* user ids should be equal to that of calling process.
*
* Algorithm:
* Setup:
* Setup signal handling.
* Pause for SIGUSR1 if option specified.
*
* Test:
* Loop if the proper options are given.
* Execute system call
* Check return code, if system call failed (return=-1)
* Log the errno and Issue a FAIL message.
* Otherwise,
* Verify the Functionality of system call
* if successful,
* Issue Functionality-Pass message.
* Otherwise,
* Issue Functionality-Fail message.
* Cleanup:
* Print errno log and/or timing stats if options given
*
* Usage: <for command-line>
* getresuid01 [-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
* 07/2001 Ported by Wayne Boyer
*
* RESTRICTIONS:
* None.
