GB_set_update_input_hint_callback

Definition

typedef void (*GB_update_input_hint_callback_t)(GB_gameboy_t *gb);

void GB_set_update_input_hint_callback(GB_gameboy_t *gb, GB_update_input_hint_callback_t callback);

In joypad.h

Description

Set the input hint callback of an emulator instance. This optional callback is called when it's "ideal" for a frontend to call GB_set_key_state, etc. Frontends that use polling for user inputs can poll in this callback to minimize input lag.

Thread Safety

If callback is not NULL, GB_set_update_input_hint_callback is thread-safe and can be called from any thread and context. Otherwise, it must not be called if the instance is being run in another thread, but may be called from the current one (via a callback).
