KDK_SYSTEM_SET_LONG_DATEFORMAT(3) Library Functions Manual NAME kdk_system_set_long_dateformat - SYNOPSIS #include extern int kdk_system_set_long_dateformat(char *format); Link with -lkydate. Detailed Description The main function of this interface is to set the long date format. The argument format is the date format, Please pass in one of the long formats. RETURN VALUE On success, returns 1 On error, return -1.
