60 * TEST CASES
61 *
62 * 1.) gethostid(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).
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).

87 * DETAILED DESCRIPTION
88 * This is a Phase I test for the gethostid(2) system call. It is intended
89 * to provide a limited exposure of the system call, for now. It
90 * should/will be extended when full functional tests are written for
91 * gethostid(2).
92 *
93 * Setup:
94 * Setup signal handling.
95 * Pause for SIGUSR1 if option specified.
96 *
97 * Test:
98 * Loop if the proper options are given.
99 * Execute system call
100 * Check return code, if system call failed (return=-1)
101 * Log the errno and Issue a FAIL message.
102 * Otherwise, Issue a PASS message.
103 *
104 * Cleanup:
105 * Print errno log and/or timing stats if options given
106 *
107 * History:
108 * 12/2002 Paul Larson - Added functional test to compare
109 * output from hostid command and gethostid()
110 *
111 * 01/2003 Robbie Williamson - Added code to handle
112 * distros that add "0x" to beginning of `hostid`
113 * output.
114 *
115 * 01/31/2006 Marty Ridgeway - Corrected 64 bit check so
116 * the second 64 bit check doesn't clobber the first 64 bit
117 * check
