- *
- * OS Test - Silicon Graphics, Inc.
- *
- * TEST IDENTIFIER : readdir01
- *
- * EXECUTED BY : anyone
- *
- * TEST TITLE : write multiple files and try to find them with readdir
- *
- * TEST CASE TOTAL :
- *
- * WALL CLOCK TIME :
- *
- * CPU TYPES : ALL
- *
- * AUTHOR : Nate Straz
- *
- * CO-PILOT :
- *
- * DATE STARTED : 02/16/2001
- *
- * INITIAL RELEASE : Linux 2.4.x
- *
- * TEST CASES
- *
- * 1.) Create n files and check that readdir() finds n files
- *
- * 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 readdir(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
- * readdir(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
- *

Hi!
Pushed with minor changes, thanks.
* Made global variables static
* Moved the path[] to the test setup
