|
|
* 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.
