59 * TEST CASES
60 *
61 * 1.) ulimit(2) returns...(See Description)
62 *
63 * INPUT SPECIFICATIONS
64 * The standard options for system call tests are accepted.
65 * (See the parse_opts(3) man page).
66 *
67 * OUTPUT SPECIFICATIONS
68 *$
69 * DURATION
70 * Terminates - with frequency and infinite modes.
71 *
72 * SIGNALS
73 * Uses SIGUSR1 to pause before test if option set.
74 * (See the parse_opts(3) man page).
75 *
76 * RESOURCES
77 * None
78 *
79 * ENVIRONMENTAL NEEDS
80 * The libcuts.a and libsys.a libraries must be included in
81 * the compilation of this test.
82 *
83 * SPECIAL PROCEDURAL REQUIREMENTS
84 * None
85 *
86 * INTERCASE DEPENDENCIES
87 * None
88 *
89 * DETAILED DESCRIPTION
90 * This is a Phase I test for the ulimit(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 * ulimit(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 *
109 *
