1.10 +** File: append.c
1.11 +** Description: Testing File writes where PR_APPEND was used on open
1.12 +**
1.13 +** append attempts to verify that a file opened with PR_APPEND
1.14 +** will always append to the end of file, regardless where the
1.15 +** current file pointer is positioned. To do this, PR_Seek() is
1.16 +** called before each write with the position set to beginning of
1.17 +** file. Subsequent writes should always append.
1.18 +** The file is read back, summing the integer data written to the
1.19 +** file. If the expected result is equal, the test passes.
1.20 +**
1.21 +** See BugSplat: 4090
