Member Function Documentation

OSoundCard * OSoundSystem::card (  const QString &  interface  )  const

Returns: a pointer to the OAudioInterface object for the specified interface or 0, if not found See also: OAudioInterface Definition at line 100 of file osoundsystem.cpp. References _interfaces.

int OSoundSystem::count (   )  const

Returns: the number of available interfaces Definition at line 94 of file osoundsystem.cpp. References _interfaces, and QDict< type >::count().

OSoundSystem * OSoundSystem::instance (   )  [static]

Returns: a pointer to the (one and only) OSystem instance. Definition at line 106 of file osoundsystem.cpp. References _instance, and OSoundSystem(). Referenced by main().

OSoundSystem::CardIterator OSoundSystem::iterator (   )  const

Returns: an iterator usable for iterating through all sound cards. Definition at line 113 of file osoundsystem.cpp. References _interfaces. Referenced by VolumeAppletControl::build(), and main().

void OSoundSystem::synchronize (   )

For internal use only. Rebuild the internal interface database Note: Sometimes it might be useful to call this from client code, e.g. after issuing a cardctl insert Definition at line 61 of file osoundsystem.cpp. References _interfaces, QDict< type >::clear(), and QDict< type >::insert(). Referenced by OSoundSystem().
