        size_t fread( void *buf, size_t size, size_t count, FILE *fp )

       - prototype in stdio.h

       - reads  (count * size)  bytes from file stream "fp"
       - returns the number of blocks actually read
       - to get better feedback from this function, the parameters "size"
         and "count" may be swapped.  If count is 1, this method allows
         fread() to return the actual number of bytes read
       - using fread or any of the stdio functions results in a default
         allocation of 512 bytes for the I/O buffer and the inclusion of
         the standard memory allocation functions
       - returns 0 (or short count) on eof or error

       - see  fopen()   fread()   setvbuf()
