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.
