Syntax

#include <stdio.h>
int feof(FILE *stream);

feof indicates whether the end-of-file flag is set for the given stream. The end-of-file flag is set by several functions to indicate the end of the file. The end-of-file flag is cleared by calling rewind, fsetpos, fseek, or clearerr for this stream.

feof returns a nonzero value if and only if the EOF flag is set; otherwise, it returns 0.

This example scans the input stream until it reads an end-of-file character.

#include <stdio.h>

int main(void)
{
   char inp_char;
   FILE *stream;

   stream = fopen("feof.dat", "r");

   /* scan an input stream until an end-of-file character is read             */

   while (0 == feof(stream)) {
      fscanf(stream, "%c", &inp_char);
      printf("<x%x> ", inp_char);
   }
   fclose(stream);
   return 0;

   /****************************************************************************
      If feof.dat contains : abc defgh

      The output should be:

      <x61> <x62> <x63> <x20> <x64> <x65> <x66> <x67> <x68>
