SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputs(const char *restrict <[s]>, FILE *restrict <[fp]>);
|
|
|
|
#define _GNU_SOURCE
|
|
#include <stdio.h>
|
|
int fputs_unlocked(const char *restrict <[s]>, FILE *restrict <[fp]>);
|
|
|
|
#include <stdio.h>
|
|
int _fputs_r(struct _reent *<[ptr]>, const char *restrict <[s]>, FILE *restrict <[fp]>);
|
|
|
|
#include <stdio.h>
|
|
int _fputs_unlocked_r(struct _reent *<[ptr]>, const char *restrict <[s]>, FILE *restrict <[fp]>);
|
|
|
|
DESCRIPTION
|
|
<<fputs>> writes the string at <[s]> (but without the trailing null)
|
|
to the file or stream identified by <[fp]>.
|
|
|
|
<<fputs_unlocked>> is a non-thread-safe version of <<fputs>>.
|
|
<<fputs_unlocked>> 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
|
|
<<fputs_unlocked>> is equivalent to <<fputs>>.
|
|
|
|
<<_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 <<EOF>>.
|
|
|
|
PORTABILITY
|
|
ANSI C requires <<fputs>>, but does not specify that the result on
|
|
success must be <<0>>; any non-negative value is permitted.
|
|
|
|
<<fputs_unlocked>> is a GNU extension.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
