|
* DETAILED DESCRIPTION
|
|
* This is a Phase I test for the stat(2) system call. It is intended
|
|
* to provide a limited exposure of the system call, for now. It
|
|
* should/will be extended when full functional tests are written for
|
|
* stat(2).
|
|
*
|
|
* 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, Issue a PASS message.
|
|
*
|
|
* Cleanup:
|
|
* Print errno log and/or timing stats if options given
|
|
*
