NAME

       SDL_hid_device_change_count - Check to see if devices may have been added or removed.

SYNOPSIS

       #include <SDL3/SDL_hidapi.h>

       Uint32 SDL_hid_device_change_count(void);

DESCRIPTION

       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.

RETURN VALUE

       Returns  a  change  counter  that is incremented with each potential device change, or 0 if device change
       detection isn't available.

AVAILABILITY

       This function is available since SDL 3.2.0.
