+ * TEST IDENTIFIER : sbrk01
+ *
+ * EXECUTED BY : anyone
+ *
+ * TEST TITLE : Basic test for sbrk(2)
+ *
+ * PARENT DOCUMENT : usctpl01
+ *
+ * TEST CASE TOTAL : 2
+ *
+ * WALL CLOCK TIME : 1
+ *
+ * CPU TYPES : ALL
+ *
+ * AUTHOR : William Roske
+ *
+ * CO-PILOT : Dave Fenner
+ *
+ * DATE STARTED : 06/05/92
+ *
+ * INITIAL RELEASE : UNICOS 7.0
+ *
+ * TEST CASES
+ *
+ * 1.) sbrk(2) returns...(See Description)
+ *
+ * INPUT SPECIFICATIONS
+ * The standard options for system call tests are accepted.
+ * (See the parse_opts(3) man page).
+ *
+ * OUTPUT SPECIFICATIONS
+ *
+ * DURATION
+ * Terminates - with frequency and infinite modes.
+ *
+ * SIGNALS
+ * Uses SIGUSR1 to pause before test if option set.
+ * (See the parse_opts(3) man page).
+ *
+ * RESOURCES
+ * None
+ *
+ * ENVIRONMENTAL NEEDS
+ * No run-time environmental needs.
+ *
+ * SPECIAL PROCEDURAL REQUIREMENTS
+ * None
+ *
+ * INTERCASE DEPENDENCIES
+ * None
+ *
+ * DETAILED DESCRIPTION
+ * This is a Phase I test for the sbrk(2) system call. It is intended
+ * to provide a limited exposure of the system call, for now. It
+ * should/will be extended when full functional tests are written for
+ * sbrk(2).
+ *
+ * Setup:
+ * Setup signal handling.
+ * Pause for SIGUSR1 if option specified.
+ *
+ * Test:
+ * Loop if the proper options are given.
+ * Execute system call
+ * Check return code, if system call failed (return=-1)
+ * Log the errno and Issue a FAIL message.
+ * Otherwise, Issue a PASS message.
+ *
+ * Cleanup:
+ * Print errno log and/or timing stats if options given
+ *
