FPUTS(3)						   BSD Library Functions Manual 						  FPUTS(3)

NAME

     fputs, puts -- output a line to a stream

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <stdio.h>

     int
     fputs(const char *restrict s, FILE *restrict stream);

     int
     puts(const char *s);

DESCRIPTION

     The function fputs() writes the string pointed to by s to the stream pointed to by stream.

     The function puts() writes the string s, and a terminating newline character, to the stream stdout.

RETURN VALUES

     The functions fputs() and puts() return a nonnegative integer on success and EOF on error.

ERRORS

     [EBADF]		The stream argument is not a writable stream.

     The functions fputs() and puts() may also fail and set errno for any of the errors specified for the routines write(2).

COMPATIBILITY

     fputs() now returns a non-negative number (as opposed to 0) on successful completion.  As a result, many tests (e.g., "fputs() == 0",
     "fputs() != 0") do not give the desired result.  Use "fputs() != EOF" or "fputs() == EOF" to determine success or failure.

SEE ALSO

     ferror(3), fputws(3), putc(3), stdio(3)

STANDARDS

     The functions fputs() and puts() conform to ISO/IEC 9899:1990 (``ISO C90'').  While not mentioned in the standard, both fputs() and puts()
     print '(null)' if str is NULL.
