FUNCTION
<<fputs>>, <<fputs_unlocked>>---write a character string in a file or stream
INDEX
fputs
INDEX
fputs_unlocked

_fputs_r
INDEX
_fputs_unlocked_r
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>>.
