| FUNCTION |
| <<time>>---get current calendar time (as single number) |
| |
| INDEX |
| time |
| |
| ANSI_SYNOPSIS |
| #include <time.h> |
| time_t time(time_t *<[t]>); |
| |
| TRAD_SYNOPSIS |
| #include <time.h> |
| time_t time(<[t]>) |
| time_t *<[t]>; |
| |
| DESCRIPTION |
| <<time>> looks up the best available representation of the current |
| time and returns it, encoded as a <<time_t>>. It stores the same |
| value at <[t]> unless the argument is <<NULL>>. |
| |
| RETURNS |
| A <<-1>> result means the current time is not available; otherwise the |
| result represents the current time. |
| |
| PORTABILITY |
| ANSI C requires <<time>>. |
| |
| Supporting OS subroutine required: Some implementations require |
| <<gettimeofday>>. |
