	__AROS_LH1(struct Message *, GetMsg,

/*  SYNOPSIS */
	__AROS_LA(struct MsgPort *, port, A0),

/*  LOCATION */
	struct ExecBase *, SysBase, 62, Exec)

/*  FUNCTION
	Get a message from a given messageport. This function doesn't wait
	and returns NULL if the messageport is empty. Therefore it's
	generally a good idea to WaitPort() or Wait() on the given port first.

    INPUTS
	port - Pointer to messageport

    RESULT
	Pointer to message removed from the port.
