Defined in header <stdio.h>

Syntax

■■■■

Remarks

ftell returns the current file pointer for stream. The offset is measured in bytes from the beginning of the file (if the file is binary).

The value returned by ftell can be used in a subsequent call to fseek.

Return value

ftell returns the current file pointer position on success. It returns -IL on error and sets the global variable errno to a positive value.

Example

#include <stdio.h>

int main(void)
{
   FILE *stream;
   stream = fopen( "MYFILE.TXT", "w+");
   fprintf (stream, "This is a test");
   printf("The file pointer  is at byte %ld\n", ftell(stream)
   fclose(stream) ;
   return 0;
