62 * 1.) lstat(2) returns...(See Description)
63 *
64 * INPUT SPECIFICATIONS
65 * The standard options for system call tests are accepted.
66 * (See the parse_opts(3) man page).

68 * OUTPUT SPECIFICATIONS
69 *$
70 * DURATION
71 * Terminates - with frequency and infinite modes.
72 *
73 * SIGNALS
74 * Uses SIGUSR1 to pause before test if option set.

89 * DETAILED DESCRIPTION
90 * This is a Phase I test for the lstat(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 * lstat(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 *
