FUNCTION

<<putc>>---write a character (macro)

INDEX

	putc

ANSI_SYNOPSIS

	#include <stdio.h>

	int putc(int <[ch]>, FILE *<[fp]>);

TRAD_SYNOPSIS

	#include <stdio.h>

	int putc(<[ch]>, <[fp]>)

	int <[ch]>;

	FILE *<[fp]>;

DESCRIPTION

<<putc>> is a macro, defined in <<stdio.h>>.  <<putc>>

writes the argument <[ch]> to the file or stream identified by

<[fp]>, after converting it from an <<int>> to an <<unsigned char>>.

If the file was opened with append mode (or if the stream cannot

support positioning), then the new character goes at the end of the

file or stream.  Otherwise, the new character is written at the

current value of the position indicator, and the position indicator

advances by one.

For a subroutine version of this macro, see <<fputc>>.

RETURNS

If successful, <<putc>> returns its argument <[ch]>.  If an error

intervenes, the result is <<EOF>>.  You can use `<<ferror(<[fp]>)>>' to

query for errors.

PORTABILITY

ANSI C requires <<putc>>; it suggests, but does not require, that

<<putc>> be implemented as a macro.  The standard explicitly permits

macro implementations of <<putc>> to use the <[fp]> argument more than once;

therefore, in a portable program, you should not use an expression

with side effects as this argument.

Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,

<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
