<>, <>---write a character on a stream or file

ANSI_SYNOPSIS

	#include 

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

	#define _BSD_SOURCE

	#include 

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

	#include 

	int _fputc_r(struct _rent *<[ptr]>, int <[ch]>, FILE *<[fp]>);

	#include 

	int _fputc_unlocked_r(struct _rent *<[ptr]>, int <[ch]>, FILE *<[fp]>);

TRAD_SYNOPSIS

	#include 

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

	int <[ch]>;

	FILE *<[fp]>;

	#define _BSD_SOURCE

	#include 

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

	int <[ch]>;

	FILE *<[fp]>;

	#include 

	int _fputc_r(<[ptr]>, <[ch]>, <[fp]>)

	struct _reent *<[ptr]>;

	int <[ch]>;

	FILE *<[fp]>;

	#include 

	int _fputc_unlocked_r(<[ptr]>, <[ch]>, <[fp]>)

	struct _reent *<[ptr]>;

	int <[ch]>;

	FILE *<[fp]>;

DESCRIPTION

<> converts the argument <[ch]> from an <> to an

<>, then writes it to the file or stream identified by

<[fp]>.

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

oadvances by one.

For a macro version of this function, see <>.

<> is a non-thread-safe version of <>.

<> may only safely be used within a scope

protected by flockfile() (or ftrylockfile()) and funlockfile().  This

function may safely be used in a multi-threaded program if and only

if they are called while the invoking thread owns the (FILE *)

object, as is the case after a successful call to the flockfile() or

ftrylockfile() functions.  If threads are disabled, then

<> is equivalent to <>.

The <<_fputc_r>> and <<_fputc_unlocked_r>> functions are simply reentrant

versions of the above that take an additional reentrant structure

argument: <[ptr]>.

RETURNS

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

intervenes, the result is <>.  You can use `<)>>' to

query for errors.

PORTABILITY

<> is required by ANSI C.

<> is a BSD extension also provided by GNU libc.

Supporting OS subroutines required: <>, <>, <>,

<>, <>, <>, <>.
