55 *
56 * DATE STARTED : 4/15/92
57 *
58 * INITIAL RELEASE : UNICOS 7.0
59 *
60 * TEST CASES
61 *
62 * mkdir(2) test for errno(s) EFAULT.
63 *
64 * INPUT SPECIFICATIONS
65 * The standard options for system call tests are accepted.
66 * (See the parse_opts(3) man page).
67 *
68 * DURATION
69 * Terminates - with frequency and infinite modes.
70 *
71 * SIGNALS
72 * Uses SIGUSR1 to pause before test if option set.
73 * (See the parse_opts(3) man page).
74 *
75 * ENVIRONMENTAL NEEDS
76 * No run-time environmental needs.
77 *
78 * DETAILED DESCRIPTION
79 * This test will verify that mkdir(2) returns a value of
80 * -1 and sets errno to EFAULT when the path argument points
81 * outside (above/below) the allocated address space of the
82 * process.
83 *
84 * Setup:
85 * Setup signal handling.
86 * Create and make current a temporary directory.
87 * Pause for SIGUSR1 if option specified.
88 *
89 * Test:
90 * Loop if the proper options are given.
91 * Execute system call
92 * Check return code, if system call failed (return=-1)
93 * Log the errno.
94 * If doing functional test
95 * check the errno returned and print result message
96 *
97 * Cleanup:
98 * Print errno log and/or timing stats if options given
99 * Remove the temporary directory.
100 * Exit.
101 *
