FUNCTION

<>---write a character string in a file or stream

INDEX

	fputs

INDEX

	_fputs_r

ANSI_SYNOPSIS

	#include 

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

	#include 

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

TRAD_SYNOPSIS

	#include 

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

	char *<[s]>;

	FILE *<[fp]>;

	#include 

	int _fputs_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]>.

<<_fputs_r>> is simply the reentrant version of <> that takes

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.

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

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