ANSI_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputs(const char *<[s]>, FILE *<[fp]>);
|
|
|
|
#include <stdio.h>
|
|
int _fputs_r(struct _reent *<[ptr]>, const char *<[s]>, FILE *<[fp]>);
|
|
|
|
TRAD_SYNOPSIS
|
|
#include <stdio.h>
|
|
int fputs(<[s]>, <[fp]>)
|
|
char *<[s]>;
|
|
FILE *<[fp]>;
|
|
|
|
#include <stdio.h>
|
|
int _fputs_r(<[ptr]>, <[s]>, <[fp]>)
|
|
struct _reent *<[ptr]>;
|
|
char *<[s]>;
|
|
FILE *<[fp]>;
|
|
|
|
DESCRIPTION
|
|
<<fputs>> writes the string at <[s]> (but without the trailing null)
|
|
to the file or stream identified by <[fp]>.
|
|
|
|
<<_fputs_r>> is simply the reentrant version of <<fputs>> that takes
|
|
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.
|
|
|
|
Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,
|
|
<<lseek>>, <<read>>, <<sbrk>>, <<write>>.
