SDL_hid_init - Man Page

Defined in SDL3/SDL_hidapi.h

#include "SDL3/SDL.h"

int SDL_hid_init(void);

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 or a negative error code on failure; call

SDL_GetError () for more information.

This function is available since SDL 3.2.0.
