ftell

#include <stdio.h>

U32 ftell (
  FILE *stream);    /* file stream */

The ftell macro gets the current file position associated with stream. The file position is an offset relative to the beginning of the stream.

The ftell function is in the RL-FlashFS library. The prototype is defined in stdio.h.

#include <rtl.h>
#include <stdio.h>

void tst_ftell (void) {
   U32 fpos;
   char line[80];
   FILE *fin;

   fin = fopen ("Counter.log","r");
   if (fin == NULL) {
      printf ("File not found!\n");
   }
   else {
      fgets (&line, sizeof (char), fin);
      // Get position after read
      fpos = ftell (fin);
      fclose (fin);
   }
}
