|
|
* 1.) fcntl(2) returns...(See Description)
|
|
*
|
|
* INPUT SPECIFICATIONS
|
|
* The standard options for system call tests are accepted.
|
|
* (See the parse_opts(3) man page).
|

* OUTPUT SPECIFICATIONS
|
|
*
|
|
* DURATION
|
|
* Terminates - with frequency and infinite modes.
|
|
*
|
|
* SIGNALS
|
|
* Uses SIGUSR1 to pause before test if option set.

|
|
* DETAILED DESCRIPTION
|
|
* This is a Phase I test for the fcntl(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
|
|
* fcntl(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
|
|
