init_subsystem

Use this function to initialize specific SDL subsystems.

SDL.init initializes assertions and crash protection and then calls SDL.init_subsystem. If you want to bypass those protections you can call SDL.init_subsystem directly.

Subsystem initialization is ref-counted, you must call SDL.quit_subsystem for each SDL.init_subsystem to correctly shutdown a subsystem manually (or call SDL.quit to force shutdown). If a subsystem is already loaded then this call will increase the ref-count and return.

Parameters:

flags

any of the flags used by SDL.init.

Returns:

Returns 0 on success or a negative error code on failure; call SDL.get_error for more information.
