PROLOG

       This  manual page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (consult the correspond-
       ing Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

NAME

       puts - put a string on standard output

SYNOPSIS

       #include <stdio.h>

       int puts(const char *s);

DESCRIPTION

       The puts() function shall write the string pointed to by s, followed by a <newline>, to the standard output stream stdout. The  terminating
       null byte shall not be written.

       The  st_ctime and st_mtime fields of the file shall be marked for update between the successful execution of puts() and the next successful
       completion of a call to fflush() or fclose() on the same stream or a call to exit() or abort().

RETURN VALUE

       Upon successful completion, puts() shall return a non-negative number. Otherwise, it shall return EOF, shall set an error indicator for the
       stream,	and errno shall be set to indicate the error.

ERRORS

       Refer to fputc().

       The following sections are informative.

EXAMPLES

   Printing to Standard Output
       The  following  example	gets  the  current time, converts it to a string using localtime() and asctime(), and prints it to standard output
       using puts(). It then prints the number of minutes to an event for which it is waiting.

	      #include <time.h>
	      #include <stdio.h>
	      ...
	      time_t now;
	      int minutes_to_event;
	      ...
	      time(&now);
	      printf("The time is ");
	      puts(asctime(localtime(&now)));
	      printf("There are %d minutes to the event.
",
		  minutes_to_event);
	      ...

APPLICATION USAGE

       The puts() function appends a <newline>, while fputs() does not.

RATIONALE

       None.

FUTURE DIRECTIONS

       None.
