puts: put a string on standard output
PROLOGThis manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.
puts - put a string on standard output
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().
Refer to fputc().
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.\n", minutes_to_event); ...
