// In header: <hpx/hpx_fwd.hpp> void register_pre_startup_function(startup_function_type const & f);
Any of the functions registered with register_pre_startup_function are guaranteed to be executed by an HPX thread before any of the registered startup functions are executed (see hpx::register_startup_function()).

|---|---|
If this function is called while the pre-startup functions are being executed or after that point, it will raise a invalid_status exception. |
This function is one of the few API functions which can be called before the runtime system has been fully initialized. It will automatically stage the provided startup function to the runtime system during its initialization (if necessary).
