  • Method Details

    • run

      void run(GError error)

      Specifies the type of function which is called when an extended error instance is freed. It is passed the error pointer about to be freed, and should free the error's private data fields.

      Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it already takes care of getting the private data from error.

      Parameters:
      error - extended error to clear

    • upcall

      default void upcall(MemorySegment error)

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
