NAME
3.20 `fwrite'--write array elements
SYNOPSIS
#include <stdio.h>
size_t fwrite(const void *BUF, size_t SIZE,
size_t COUNT, FILE *FP);
DESCRIPTION
`fwrite' attempts to copy, starting from the memory location BUF, COUNT
elements (each of size SIZE) into the file or stream identified by FP.
`fwrite' may copy fewer elements than COUNT if an error intervenes.
`fwrite' also advances the file position indicator (if any) for FP
by the number of _characters_ actually written.
RETURNS
If `fwrite' succeeds in writing all the elements you specify, the
result is the same as the argument COUNT. In any event, the result is
the number of complete elements that `fwrite' copied to the file.
PORTABILITY
ANSI C requires `fwrite'.
Supporting OS subroutines required: `close', `fstat', `isatty',
`lseek', `read', `sbrk', `write'.
