Detailed Description

MIDI Driver for Linux Alsa based machines

Definition at line 30 of file AlsaDriver.h.

Member Enumeration Documentation


Async procedure is running - use WaitTillDone() to wait for completion.


Async procedure completed running - use StopTimer() to finish.


No background procedure running - use StartTimer() to start one.

Member Function Documentation

bool CFugue::MIDIDriverAlsa::OpenMIDIInPort ( int  id)

Opens the MIDI input port with the given ID

false if the given input port cannot be opened

Definition at line 35 of file AlsaDriver.cpp.

bool CFugue::MIDIDriverAlsa::OpenMIDIOutPort ( int  id)

Opens the MIDI output port with the given ID

false if the given output port cannot be opened

Definition at line 70 of file AlsaDriver.cpp.

bool CFugue::MIDIDriverAlsa::StartTimer ( int  resolution_ms)

Creates a background thread to pump MIDI events at the supplied timer resolution. Use WaitTillDone() to wait till the background processing completes. Use StopTimer() after the background processing is completed, to release resources.

resolution_msMIDI Timer resolution in milliseconds
false if background thread cannot be started

Definition at line 151 of file AlsaDriver.cpp.

void CFugue::MIDIDriverAlsa::StopTimer ( )

Call StopTimer() to release the resources used by the background procedure created with StartTimer(). StopTimer() Should be called after the background procedure is done (indicated by BGThreadStatus::COMPLETED). If background procedure is still running while StopTimer() is called, caller gets blocked till the background procedure completes. If no background procedure exists, returns immediately.

Definition at line 173 of file AlsaDriver.cpp.

void CFugue::MIDIDriverAlsa::WaitTillDone ( )

Waits (blocks) till the background thread created with StartTimer() completes its processing. After StartTimer() succeeds, use WaitTillDone() followed by StopTimer(). Returns immediately if no background thread is running.
