sdlHidRead function

int sdlHidRead(Pointer<SdlHidDevice> dev, Pointer<Uint8> data, int length)

Read an Input report from a HID device.

Input reports are returned to the host through the INTERRUPT IN endpoint. The first byte will contain the Report number if the device uses numbered reports.

\param dev a device handle returned from SDL_hid_open(). \param data a buffer to put the read data into. \param length the number of bytes to read. For devices with multiple reports, make sure to read an extra byte for the report number. \returns the actual number of bytes read and -1 on failure; call SDL_GetError() for more information. If no packet was available to be read and the handle is in non-blocking mode, this function returns 0.

\since This function is available since SDL 3.1.3.
