37 * TEST IDENTIFIER : alarm01
39 * EXECUTED BY : anyone
41 * TEST TITLE : Basic test for alarm(2)
43 * PARENT DOCUMENT : usctpl01
51 * AUTHOR : William Roske
53 * CO-PILOT : Dave Fenner
55 * DATE STARTED : 03/30/92
57 * INITIAL RELEASE : UNICOS 7.0
61 * 1.) alarm(2) returns...(See Description)
63 * INPUT SPECIFICATIONS
64 * The standard options for system call tests are accepted.
65 * (See the parse_opts(3) man page).
67 * OUTPUT SPECIFICATIONS
70 * Terminates - with frequency and infinite modes.
73 * Uses SIGUSR1 to pause before test if option set.
74 * (See the parse_opts(3) man page).
80 * The libcuts.a and libsys.a libraries must be included in
81 * the compilation of this test.
83 * SPECIAL PROCEDURAL REQUIREMENTS
86 * INTERCASE DEPENDENCIES
89 * DETAILED DESCRIPTION
90 * This is a Phase I test for the alarm(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
96 * Setup signal handling.
97 * Pause for SIGUSR1 if option specified.
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.
107 * Print errno log and/or timing stats if options given
