fputs: dát řetězec do proudu

Originální popis anglicky: fputs - put a string on a stream

Návod, kniha: POSIX Programmer's Manual

STRUČNĚ

#include <stdio.h>
 
 
int fputs(const char *restrict s, FILE *restrict stream);
 

POPIS / INSTRUKCE

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().

NÁVRATOVÁ HODNOTA

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.

PŘÍKLADY POUŽITÍ

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.
