Code:
void enet_svsend_event(var type, char* msg, var length, var receiver) 
void enet_svsend_event(var type, STRING* msg, var receiver) 
void enet_clsend_event(var type, char* msg, var length, var receiver) 
void enet_clsend_event(var type, STRING* msg, var receiver);

When you send a string by enet_clsend_event, you should not write length of string in it.

Code:
void sendev()
{
	enet_clsend_event(25,"",BROADCAST);
}
