    25 FUNCTION

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

    27 

    28 INDEX

    29 	fputs

    30 

    31 ANSI_SYNOPSIS

    32 	#include <stdio.h>

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

    34 

    35 TRAD_SYNOPSIS

    36 	#include <stdio.h>

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

    38 	char *<[s]>;

    39 	FILE *<[fp]>;

    40 

    41 DESCRIPTION

    42 <<fputs>> writes the string at <[s]> (but without the trailing null)

    43 to the file or stream identified by <[fp]>.

    44 

    45 RETURNS

    46 If successful, the result is <<0>>; otherwise, the result is <<EOF>>.

    47 

    48 PORTABILITY

    49 ANSI C requires <<fputs>>, but does not specify that the result on

    50 success must be <<0>>; any non-negative value is permitted.

    51 

    52 Supporting OS subroutines required: <<close>>, <<fstat>>, <<isatty>>,

    53 <<lseek>>, <<read>>, <<sbrk>>, <<write>>.
