FMOD_SYSTEM_CALLBACK_TYPE

These callback types are used with System::setCallback.

Each callback has commanddata parameters passed as void* unique to the type of callback.
See reference to FMOD_SYSTEM_CALLBACK to determine what they might mean for each type of callback.

Note! Using FMOD_SYSTEM_CALLBACK_DEVICELISTCHANGED (on Mac only) requires the application to be running an event loop which will allow external changes to device list to be detected by FMOD.

Note! The 'system' object pointer will be null for FMOD_SYSTEM_CALLBACK_THREADCREATED and FMOD_SYSTEM_CALLBACK_MEMORYALLOCATIONFAILED callbacks.

Values

FMOD_SYSTEM_CALLBACK_DEVICELISTCHANGED

Called from System::update when the enumerated list of devices has changed.

FMOD_SYSTEM_CALLBACK_DEVICELOST

Called from System::update when an output device has been lost due to control panel parameter changes and FMOD cannot automatically recover.

FMOD_SYSTEM_CALLBACK_MEMORYALLOCATIONFAILED

Called directly when a memory allocation fails somewhere in FMOD. (NOTE - 'system' will be NULL in this callback type.)

FMOD_SYSTEM_CALLBACK_THREADCREATED

Called directly when a thread is created. (NOTE - 'system' will be NULL in this callback type.)

FMOD_SYSTEM_CALLBACK_BADDSPCONNECTION

Called when a bad connection was made with DSP::addInput. Usually called from mixer thread because that is where the connections are made.

FMOD_SYSTEM_CALLBACK_PREMIX

Called each tick before a mix update happens.

FMOD_SYSTEM_CALLBACK_POSTMIX

Called each tick after a mix update happens.

FMOD_SYSTEM_CALLBACK_ERROR

Called when each API function returns an error code, including delayed async functions.
