KDK_SYSTEM_LOGN_DATEINFO(3) Library Functions Manual NAME kdk_system_logn_dateinfo - SYNOPSIS #include extern kdk_logn_dateinfo *kdk_system_logn_dateinfo(char *user); Link with -lkydate. Detailed Description The main function of this interface is to obtain the time and date of the login interface when no user is logged in. The argument user is the user name RETURN VALUE On success, returns a pointer to a kdk_logn_dateinfo structure is defined in as follows: typedef struct _kdk_logn_dateinfo{ char *date; // char *time; // char *week; }kdk_logn_dateinfo; On error, return NULL.
