fputs - put a string on a stream
#include <stdio.h>
int fputs(const char *restrict s, FILE *restrict stream);
The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.
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().
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.
Refer to fputc() .
The following sections are informative.
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);
...
The puts() function appends a <newline> while fputs() does not.
