KDK_SYSTEM_GET_NOW_DATEFORMAT(3)                      Library Functions Manual

NAME
       kdk_system_get_now_dateformat - <?><?><?><?><?><?><?><?><?>

SYNOPSIS
       #include <libkydate.h>

       extern char* kdk_system_get_now_dateformat();

       Link with -lkydate.

Detailed Description
       The main function of this interface is to obtain the current date
       format of the system.

RETURN VALUE
       On success, returns the current date format with type of char*; The
       returned string needs to be released by free

       On error, return NULL.
