| /* |
| * Test Name: ftruncate03 |
| * |
| * Test Description: |
| * Verify that, |
| * 1) ftruncate(2) returns -1 and sets errno to EINVAL if the specified |
| * socket is invalid. |
| * 2) ftruncate(2) returns -1 and sets errno to EINVAL if the specified |
| * file descriptor has an attempt to write, when open for read only. |
| * 3) ftruncate(2) returns -1 and sets errno to EBADF if the file descriptor |
| * of the specified file is not valid. |
| * |
| * Expected Result: |
| * ftruncate() should fail with return value -1 and set expected errno. |
| * |
| * HISTORY |
| * 02/2002 Written by Jay Huie |
| * 02/2002 Adapted for and included into the LTP by Robbie Williamson |
| * |
| * RESTRICTIONS: |
| * This test should be run by 'non-super-user' only. |
