.SH NAME
|
|
.BR fputc ,
|
|
.BR putc ,
|
|
.BR putchar ,
|
|
.BR putw
|
|
\- output a character or word to a stream
|
|
.SH SYNOPSIS
|
|
#include <stdio.h>
|
|
.sp 1
|
|
int \fBfputc\fR (int \fIc\fR, FILE *\fIstream\fR);
|
|
.br
|
|
int \fBputc\fR (int \fIc\fR, FILE *\fIstream\fR);
|
|
.br
|
|
int \fBputchar\fR (int \fIc\fR);
|
|
.br
|
|
int \fBputw\fR (int \fIw\fR, FILE *\fIstream\fR);
|
|
.SH DESCRIPTION
|
|
The
|
|
.BR fputc
|
|
function
|
|
writes the character
|
|
.I c
|
|
(converted to an ``unsigned char'')
|
|
to the output stream pointed to by
|
|
.IR stream .
|
|
.LP
|
|
.BR Putc
|
|
acts essentially identically to
|
|
.BR fputc ,
|
|
but is a macro that expands in-line. It may evaluate
|
|
.I stream
|
|
more than once, so arguments given to
|
|
.BR putc
|
|
should not be expressions with potential side effects.
|
|
.LP
|
|
.BR Putchar
|
|
is identical to
|
|
.BR putc
|
|
with an output stream of
|
|
.IR stdout .
|
|
.LP
|
|
The
|
|
.BR putw
|
|
function
|
|
writes the specified
|
|
.IR int
|
|
to the named output
|
|
.IR stream .
|
|
.SH RETURN VALUES
|
|
The functions,
|
|
.BR fputc ,
|
|
.BR putc
|
|
and
|
|
.BR putchar
|
|
return the character written.
|
|
If an error occurs, the value
|
|
.BR EOF
|
|
is returned.
|
|
The
|
|
.BR putw
|
|
function
|
|
returns 0 on success;
|
|
.BR EOF
|
|
is returned if
|
|
a write error occurs,
|
|
or if an attempt is made to write a read-only stream.
|
|
.SH SEE ALSO
|
|
.BR ferror (3),
|
|
.BR fopen (3),
|
|
.BR getc (3),
|
|
.BR stdio (3)
|
|
.SH STANDARDS
|
|
The functions
|
|
.BR fputc ,
|
|
.BR putc ,
|
|
and
|
|
.BR putchar ,
|
|
conform to ANSI/C.
|
|
A function
|
|
.BR putw
|
|
function appeared in
|
|
.BR v6 .
|
|
.SH BUGS
|
|
The size and byte order of an
|
|
.IR int
|
|
varies from one machine to another, and
|
|
.BR putw
|
|
is not recommended for portable applications.
