FPUTS(P) POSIX Programmer's Manual FPUTS(P)NAMEfputs - put a string on a stream
SYNOPSIS
#include <stdio.h>
int fputs(const char *restrict s, FILE *restrict stream);
DESCRIPTION
The fputs() function shall write the null-terminated string pointed to
by s to the stream pointed to by stream. 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 fputs() 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, fputs() shall return a non-negative number.
Otherwise, it shall return EOF, set an error indicator for the stream,
and set errno to indicate the error.
ERRORS
Refer to fputc() .

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
fputs(). 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 ");
fputs(asctime(localtime(&now)), stdout);
printf("There are still %d minutes to the event.\n",
minutes_to_event);
...
APPLICATION USAGE
The puts() function appends a <newline> while fputs() does not.
RATIONALE
None.
FUTURE DIRECTIONS
None.
