Summary

0000420: ftell reports wrong position

Description

When opening a file with fopen(file, "a"), the data is appended correctly, but the file position is illegal. It is 0 at the start of writing, whereas it should be the file size

The following example shows this problem. The numbers outputted should differ only by 1 and not by filesize as they do now.

#include <stdio.h>

int main(void)
{
  FILE *fh;
  int i;
  fh = fopen("shit", "ab");
  i = fseek(fh, 0, SEEK_END);
  fprintf(fh, "x");
  printf("%d %d\n", i, ftell(fh));
  fclose(fh);
  fh = fopen("shit", "ab");
  fprintf(fh, "\n");
  printf("%d %d\n", i, ftell(fh));
  fclose(fh);
  return 0;
}
