| FUNCTION |
| <<localtime>>---convert time to local representation |
| |
| INDEX |
| localtime |
| INDEX |
| localtime_r |
| |
| ANSI_SYNOPSIS |
| #include <time.h> |
| struct tm *localtime(time_t *<[clock]>); |
| struct tm *localtime_r(time_t *<[clock]>, struct tm *<[res]>); |
| |
| TRAD_SYNOPSIS |
| #include <time.h> |
| struct tm *localtime(<[clock]>) |
| time_t *<[clock]>; |
| struct tm *localtime(<[clock]>, <[res]>) |
| time_t *<[clock]>; |
| struct tm *<[res]>; |
| |
| DESCRIPTION |
| <<localtime>> converts the time at <[clock]> into local time, then |
| converts its representation from the arithmetic representation to the |
| traditional representation defined by <<struct tm>>. |
| |
| <<localtime>> constructs the traditional time representation in static |
| storage; each call to <<gmtime>> or <<localtime>> will overwrite the |
| information generated by previous calls to either function. |
| |
| <<mktime>> is the inverse of <<localtime>>. |
| |
| RETURNS |
| A pointer to the traditional time representation (<<struct tm>>). |
| |
| PORTABILITY |
| ANSI C requires <<localtime>>. |
| |
| <<localtime>> requires no supporting OS subroutines. |
