Method

MaplibreNativeFfiRenderSessionbarrier_async

Declaration [src] 

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

Description [src]

Ends the session’s pending frame demands and waits for its earlier work.

Frame demands that haven’t started, including those that wait for a map update, finish with MAPLIBRE_NATIVE_FFI_RENDER_RESULT_NO_UPDATE.

See mln_render_session_barrier in the C API reference.

It fails with these errors:

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

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

The callback to call when the call finishes.

The argument can be NULL.
user_data
