rt_status_t GRUEL_API	enable_realtime_scheduling (rt_sched_param=rt_sched_param())
	If possible, enable "realtime" scheduling.In general, this means that the code will be scheduled before any non-realtime (normal) processes. Note that if your code contains an non-blocking infinite loop and you enable realtime scheduling, it's possible to hang the system.

static pmt::pmt_t gruel::send ( msg_accepter_sptr  accepter, const pmt::pmt_t &  msg  )

inlinestatic

send message to msg_accepter

Parameters:

accepter	is the target of the send.
msg	is the message to send. It's usually a pmt tuple.

Sending a message is an asynchronous operation. The send call will not wait for the message either to arrive at the destination or to be received.

Returns:

msg

Parameters:

accepter	is the target of the send.
msg	is the message to send. It's usually a pmt tuple.

Sending a message is an asynchronous operation. The send call will not wait for the message either to arrive at the destination or to be received.
