Method

MaplibreNativeFfiRenderSessiondetach_async

Declaration [src] 

void
maplibre_native_ffi_render_session_detach_async (
  MaplibreNativeFfiRenderSession* self,
  GAsyncReadyCallback callback,
  gpointer user_data
)

Description [src]

Detaches the session from its map and frees its graphics objects.

Release every acquired frame first. Pending frame demands finish with MAPLIBRE_NATIVE_FFI_RENDER_RESULT_TARGET_NOT_READY. Once the detach completes, the library no longer uses your graphics objects, and you can attach another session to the map. Release the session afterward.

See mln_render_session_detach in the C API reference.

It fails with these errors:

  • MAPLIBRE_NATIVE_FFI_ERROR_TARGET_LOST when the session loses its target before the detach runs.

This method completes asynchronously. Use maplibre_native_ffi_render_session_detach_finish() inside the GAsyncReadyCallback to obtain the result of the operation.
