/**********************************************************
*
* OS Test - Silicon Graphics, Inc.
*
* TEST IDENTIFIER : unlink08
*
* EXECUTED BY : anyone
*
* TEST TITLE : unlink(2) negative testcases
*
* PARENT DOCUMENT : usctpl01
*
* TEST CASE TOTAL : 3
*
* WALL CLOCK TIME : 1
*
* CPU TYPES : ALL
*
* AUTHOR : Richard Logan
*
* CO-PILOT : William Roske
*
* DATE STARTED : 03/30/94
*
* INITIAL RELEASE : UNICOS 7.0
*
* TEST CASES
*
* 1-3) See Testcases structure below.
*
* 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.
* (See the parse_opts(3) man page).
*
* RESOURCES
* None
*
* ENVIRONMENTAL NEEDS
* No run-time environmental needs.
*
* SPECIAL PROCEDURAL REQUIREMENTS
* None
*
* INTERCASE DEPENDENCIES
* None
*
* DETAILED DESCRIPTION
* This is a Phase I test for the unlink(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
* unlink(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
*
