The C API provides an extension finalization function for
the runtime to call when it unloads the extension. However, the
runtime does not always unload an extension. Therefore, the runtime
does not always call the extension finalization function.
Define your extension finalization function with the signature
of
FREFinalizer()
. This method has one
input parameter: the extension data you created in your extension
initialization function. Clean up any data and resources associated with
this extension.
For application-bundled extensions, your implementation of
FREFinalizer()
can
have any name. Specify the name of the finalization function in
the extension descriptor file. See
Native extension descriptor files
.
For device-bundled applications, how to specify the extension
finalization function is device-dependent.
