下面这段代码能实现枚举吗？
/*================= EnumUsers ==================*/
#define PWGENENUMUSERS_NAME _T("PWGENEnumUsers")
BOOL WINAPI PWGENEnumUsers(LPDWORD dwCount, // receives number of users
PWGEN_ENUM_USERS_CALLBACK cfn, // enumeration callback
PVOID userdata, // individual userdata, passed to callback
LPCMN_ERROR error);
typedef BOOL (WINAPI *PWGENEnumUsersFCT)(LPDWORD dwCount, PWGEN_ENUM_USERS_CALLBACK cfn, PVOID userdata, LPCMN_ERROR error);
