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.
GRUEL_API void mask_signals ()

Detailed Description

Include this header to use the message passing features.

System independent way to ask for realtime scheduling.

static pmt::pmt_t gruel::send ( msg_accepter *  accepter,
const pmt::pmt_t msg 
) [inline, static]

send message to msg_accepter

Parameters:
accepteris the target of the send.
msgis 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

accepteris the target of the send.
msgis the message to send. It's usually a pmt tuple.
