|

* Test Name: poll01
|
||||
*
|
||||
* Test Description:
|
||||
* Verify that valid open file descriptor must be provided to poll() to
|
||||
* succeed.
|
||||
*
|
||||
* Expected Result:
|
||||
* poll should return the correct values when an valid file descriptor is
|
||||
* provided.
|
||||
*
|
||||
* 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)
|
||||
* 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>
|
||||
* poll01 [-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.
