sdlHidGetReportDescriptor function

int sdlHidGetReportDescriptor(Pointer<SdlHidDevice> dev, Pointer<Uint8> buf, int bufSize)

Get a report descriptor from a HID device.

User has to provide a preallocated buffer where descriptor will be copied to. The recommended size for a preallocated buffer is 4096 bytes.

\param dev a device handle returned from SDL_hid_open(). \param buf the buffer to copy descriptor into. \param buf_size the size of the buffer in bytes. \returns the number of bytes actually copied or -1 on failure; call SDL_GetError() for more information.

\since This function is available since SDL 3.1.3.
