= SDL_hid_device_change_count = Check to see if devices may have been added or removed. == Syntax == Uint32 SDL_hid_device_change_count(void); == Return Value == Returns a change counter that is incremented with each potential device change, or 0 if device change detection isn't available. == Remarks == Enumerating the HID devices is an expensive operation, so you can call this to see if there have been any system device changes since the last call to this function. A change in the counter returned doesn't necessarily mean that anything has changed, but you can call [[SDL_hid_enumerate]]() to get an updated device list. Calling this function for the first time may cause a thread or other system resource to be allocated to track device change notifications. == Version == This function is available since SDL 2.0.18. == Related Functions == :[[SDL_hid_enumerate]] ---- [[CategoryAPI]]
