FUNCTION
<<fputs>>---write a character string in a file or stream
INDEX
fputs
INDEX
_fputs_r
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>>.
