Tests for end-of-file on a stream.

int feof(    FILE*stream);

Parameters

  • stream
    Pointer to FILE structure.

Return Values

The feof function returns a nonzero value after the first read operation that attempts to read past the end of the file.

It returns 0 if the current position is not end of file.

There is no error return.

Remarks

The feof routine (implemented both as a function and as a macro) determines whether the end of stream has been reached.

When end of file is reached, read operations return an end-of-file indicator until the stream is closed or until fsetpos, fseek, or clearerr is called against it.

Example

/* FEOF.C: This program uses feof to indicate when
 * it reaches the end of the file FEOF.C. It also
 * checks for errors with ferror.
 */

#include <stdio.h>
#include <stdlib.h>

void main( void )
{
   int  count, total = 0;
   char buffer[100];
   FILE *stream;

   if( (stream = fopen( "feof.c", "r" )) == NULL )
      exit( 1 );

   /* Cycle until end of file reached: */
   while( !feof( stream ) )
   {
      /* Attempt to read in 10 bytes: */
      count = fread( buffer, sizeof( char ), 100, stream );
      if( ferror( stream ) )      {
         printf( "Read error" );
         break;
      }

      /* Total up actual bytes read */
      total += count;
   }
   printf( "Number of bytes read = %d\n", total );
   fclose( stream );
}

Output

Number of bytes read = 745

Requirements

OS Versions: Windows CE 2.0 and later.
Header: stdlib.h.
Link Library: coredll.dll.
