Firelight Technologies FMOD Studio API
FMOD_DSP_SYSTEM_DEREGISTER_CALLBACK
This callback is called when the user unloads a DSP plugin, or shuts down FMOD using System::close or System::release. The function can be used as a 'one off' shut down for the plugin after all instances have been freed.
C/C++ Syntax
FMOD_RESULT F_CALLBACK FMOD_DSP_SYSTEM_DEREGISTER_CALLBACK(
FMOD_DSP_STATE *dsp_state
);
Parameters
dsp_state
Pointer to the plugin state. The user can use this variable to access runtime plugin specific variables and plugin writer user data. Do not cast this to FMOD_DSP! The instance pointer in the state for this callback will be 0 / null. Only 'systemobject' and 'callbacks' are valid for use.
Return Values
If the function succeeds then the return value is FMOD_OK.
If the function fails then the return value will be one of the values defined in the FMOD_RESULT enumeration.
Remarks
The callback is not associated with any DSP instance, so the instance member of FMOD_DSP_STATE will be 0 / NULL. Functions that the user would have to call for this callback to be called.
Remember to return FMOD_OK at the bottom of the function, or an appropriate error code from FMOD_RESULT.
