I found the file hidapi/windows/hid.c, include codes

HID_API_EXPORT hid_device * HID_API_CALL hid_open_path(const char *path)
{
....
	/* Set the Input Report buffer size to 64 reports. */
	res = HidD_SetNumInputBuffers(dev->device_handle, 64);
	if (!res) {
		register_error(dev, "HidD_SetNumInputBuffers");
		goto err;
	}
...
}

how to call it HidD_SetNumInputBuffers
