Návod, kniha: POSIX Programmer's Manual
#include <stdio.h>
int puts(const char *
s);
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().
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.
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
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);
...
The
puts() function appends a <newline>, while
fputs() does
not.
None.
None.
