89 * DETAILED DESCRIPTION
90 * This is a Phase I test for the unlink(2) system call. It is intended
91 * to provide a limited exposure of the system call, for now. It
92 * should/will be extended when full functional tests are written for
93 * unlink(2).
94 *
95 * Setup:
96 * Setup signal handling.
97 * Pause for SIGUSR1 if option specified.
98 *
99 * Test:
100 * Loop if the proper options are given.
101 * Execute system call
102 * Check return code, if system call failed (return=-1)
103 * Log the errno and Issue a FAIL message.
104 * Otherwise, Issue a PASS message.
105 *
106 * Cleanup:
107 * Print errno log and/or timing stats if options given
108 *
