<h3>WRITE(3) Linux Programmer's Manual WRITE(3)
</h3>
<h3>NAME
</h3> fread, fwrite - binary stream input/output
<h3>SYNOPSIS
</h3> #include <stdio.h>
int fread( void *ptr, size_t size, size_t nmemb, FILE
*stream);
int fwrite( void *ptr, size_t size, size_t nmemb, FILE
*stream);
<h3>DESCRIPTION
</h3> The function fread reads nmemb elements of data, each size
bytes long, from the stream pointed to by stream, storing
them at the location given by ptr.
The function fwrite writes nmemb elements of data, each
size bytes long, to the stream pointed to by stream,
obtaining them from the location given by ptr.
<h3>RETURN VALUES
</h3> fread and fwrite return the number of items successfully
read or written (i.e., not the number of characters). If
an error occurs, or the end-of-file is reached, the return
value is a short item count (or zero).
fread does not distinguish between end-of-file and error,
and callers must use feof(3) and ferror(3) to determine
which occurred.
