Function SDL_hid_init

pub unsafe extern "C" fn SDL_hid_init() -> i32
Available on crate feature dep_sdl3 only.
Expand description

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()

§Return value

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

§Availability

This function is available since SDL 3.2.0.
