| 7 ** File: append.c | |
| 8 ** Description: Testing File writes where PR_APPEND was used on open | |
| 9 ** | |
| 10 ** append attempts to verify that a file opened with PR_APPEND | |
| 11 ** will always append to the end of file, regardless where the | |
| 12 ** current file pointer is positioned. To do this, PR_Seek() is | |
| 13 ** called before each write with the position set to beginning of | |
| 14 ** file. Subsequent writes should always append. | |
| 15 ** The file is read back, summing the integer data written to the | |
| 16 ** file. If the expected result is equal, the test passes. | |
| 17 ** | |
| 18 ** See BugSplat: 4090 | |
