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