feof

Usage

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

   ANSI

Description

   feof determines if the stream fp is at the end of file. After the EOF
   indicator is set no further read operations are allowed.

Example 

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

   #define BUFSIZE 128
   char buffer[BUFSIZE];

   int main()
   {
       FILE *fp;
       fp = fopen ("file.dat", "r");
           {
               while ( !feof(fp) )
                   fgets(buffer, BUFSIZE, fp);
           }
       printf("Done reading file, EOF found\n",buffer);
       return EXIT_SUCCESS;
   }

Return Value

   Non-zero (EOF flag set) if current position is end. No read operations
   are allowed after the flag is set. The flag is cleared if rewind, fseek
   or file is closed. 0 if the flag is clear.
