Gimpquit

Forcefully causes the GIMP library to exit and close down its connection to main gimp application. This function never returns.

It is highly unadvised to use this function since the plug-in will not properly return. If you need to return from a plug-in in error, gracefully return with gimp_procedure_new_return_values() setting GimpPDBStatusType as a status and with a well written GError message to display.
