FPUTS(3)               FreeBSD Library Functions Manual               FPUTS(3)

NAME
     fputs, fputs_unlocked, puts - output a line to a stream

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <stdio.h>

     int
     fputs(const char *str, FILE *stream);

     int
     fputs_unlocked(const char *str, FILE *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 fputs_unlocked() function is equivalent to fputs(), except that the
     caller is responsible for locking the stream with flockfile(3) before
     calling it.  This function may be used to avoid the overhead of locking
     the stream and to prevent races when multiple threads are operating on
     the same stream.

     The function puts() writes the string str, 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).

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

STANDARDS
     The functions fputs() and puts() conform to ISO/IEC 9899:1990
     ("ISO C90").
