qnx_trigger (pid, command, priority? )
The process ID of the proxy.
The message code.
The priority of the message.
This function is a mapping of the QNX 4 kernel function Trigger. It triggers a proxy to send its message to the receiving task. Its calling process does not block, and if more than one qnx_trigger call is sent while the task is busy, up to 65535 proxy messages will be queued for later delivery.
In case of error, the errno ESRCH means the proxy does not exist.
