nstraz | fa31d55 | 2002-05-14 16:50:06 +0000 | [diff] [blame] | 21 | * Test Name: fstat04 |
plars | 865695b | 2001-08-27 22:15:12 +0000 | [diff] [blame] | 22 | * |
| 23 | * Test Description: |
| 24 | * Verify that, fstat(2) succeeds to get the status of a file pointed by |
| 25 | * file descriptor and fills the stat structure elements. |
| 26 | * |
| 27 | * Expected Result: |
| 28 | * fstat() should return value 0 on success and the stat structure should |
| 29 | * be filled with specified 'file' information. |
| 30 | * |
| 31 | * Algorithm: |
| 32 | * Setup: |
| 33 | * Setup signal handling. |
| 34 | * Create temporary directory. |
| 35 | * Pause for SIGUSR1 if option specified. |
| 36 | * |
| 37 | * Test: |
| 38 | * Loop if the proper options are given. |
| 39 | * Execute system call |
| 40 | * Check return code, if system call failed (return=-1) |
| 41 | * Log the errno and Issue a FAIL message. |
| 42 | * Otherwise, |
| 43 | * Verify the Functionality of system call |
| 44 | * if successful, |
| 45 | * Issue Functionality-Pass message. |
| 46 | * Otherwise, |
| 47 | * Issue Functionality-Fail message. |
| 48 | * Cleanup: |
| 49 | * Print errno log and/or timing stats if options given |
| 50 | * Delete the temporary directory created. |
| 51 | * |
| 52 | * Usage: <for command-line> |
