fread

Usage

   #include <stdio.h>
   size_t fread(const void *p,size_t sizelem,size_t n,FILE *fp);

   ANSI

Description

   Reads n elements from stream fp into the array that p points to. sizelem
   is the number of bytes in each element.

Example 

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

   int main()
   {
       char *dest;
       int size = 1;
       int number = 256, numread;
       FILE *fp;
       if((fp = fopen("file.dat","r")) == NULL)
           return EXIT_FAILURE;
       dest = calloc(256,1);

       numread = fread(dest,size,number,fp);
       printf("Total read %d\n",numread);
       fprintf(stdout,"Data read\n %s",dest);
       free(dest);
       return EXIT_SUCCESS;
   }

Return Value

   fread returns the number of complete elements actually read. If an error
   or an end of file is encountered, it will return less than n.
