Function sdl2_sys::SDL_hid_init

pub unsafe extern "C" fn SDL_hid_init() -> c_int

Initialize the HIDAPI library.

This function initializes the HIDAPI library. Calling it is not strictly necessary, as it will be called automatically by SDL_hid_enumerate() and any of the SDL_hid_open_*() functions if it is needed. This function should be called at the beginning of execution however, if there is a chance of HIDAPI handles being opened by different threads simultaneously.

Each call to this function should have a matching call to SDL_hid_exit()

\returns 0 on success and -1 on error.

\since This function is available since SDL 2.0.18.
