    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>>.
