INDEX

INDEX

	_fputs_unlocked_r

ANSI_SYNOPSIS

	#include 

	int fputs(const char *restrict <[s]>, FILE *restrict <[fp]>);

	#define _GNU_SOURCE

	#include 

	int fputs_unlocked(const char *restrict <[s]>, FILE *restrict <[fp]>);

	#include 

	int _fputs_r(struct _reent *<[ptr]>, const char *restrict <[s]>, FILE *restrict <[fp]>);

	#include 

	int _fputs_unlocked_r(struct _reent *<[ptr]>, const char *restrict <[s]>, FILE *restrict <[fp]>);

TRAD_SYNOPSIS

	#include 

	int fputs(<[s]>, <[fp]>)

	char *<[s]>;

	FILE *<[fp]>;

	#define _GNU_SOURCE

	#include 

	int fputs_unlocked(<[s]>, <[fp]>)

	char *<[s]>;

	FILE *<[fp]>;

	#include 

	int _fputs_r(<[ptr]>, <[s]>, <[fp]>)

	struct _reent *<[ptr]>;

	char *<[s]>;

	FILE *<[fp]>;

	#include 

	int _fputs_unlocked_r(<[ptr]>, <[s]>, <[fp]>)

	struct _reent *<[ptr]>;

	char *<[s]>;

	FILE *<[fp]>;

DESCRIPTION

<> writes the string at <[s]> (but without the trailing null)

to the file or stream identified by <[fp]>.

<> 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 <>.

<<_fputs_r>> and <<_fputs_unlocked_r>> are simply reentrant versions of the

above that take an additional reentrant struct pointer argument: <[ptr]>.

RETURNS

If successful, the result is <<0>>; otherwise, the result is <>.

PORTABILITY

ANSI C requires <>, but does not specify that the result on

success must be <<0>>; any non-negative value is permitted.

<> is a GNU extension.

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

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