- * DATE STARTED : 03/30/94
- *
- * INITIAL RELEASE : UNICOS 7.0
- *
- * TEST CASES
- *
- * 1-8) 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

- *
- * 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

+ * Description:
+ * The testcase checks the various errnos of the unlink(2).
+ * 1) unlink() returns ENOENT if file doesn't exist.
+ * 2) unlink() returns ENOENT if path is empty.
+ * 3) unlink() returns ENOENT if path contains a non-existent file.
+ * 4) unlink() returns EFAULT if address beyond address space.
+ * 5) unlink() returns ENOTDIR if path contains a regular file.
+ * 6) unlink() returns ENAMETOOLONG if path contains a regular file.
+ * 7) unlink() returns EFAULT if address is negative.
