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 str, FILE * restrict stream);

     int
     puts(const char *str);

DESCRIPTION

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

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

RETURN VALUES

     The fputs() function returns 0 on success and EOF on error; puts() returns a nonnegative integer on success and EOF on error.

ERRORS

     [EBADF]		The stream supplied 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).

SEE ALSO

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

STANDARDS

     The functions fputs() and puts() conform to ANSI X3.159-1989 (``ANSI C89'').

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.
