Detect failure of device information read
If the received data is smaller than the device information size, then
something is wrong.
SDL_bool device_read_info(socket_t device_socket, char *device_name, struct size *size) {
unsigned char buf[DEVICE_NAME_FIELD_LENGTH + 4];
- if (net_recv(device_socket, buf, sizeof(buf)) <= 0) {
+ int r = net_recv(device_socket, buf, sizeof(buf));
+ if (r < DEVICE_NAME_FIELD_LENGTH + 4) {
LOGE("Could not retrieve device information");
return SDL_FALSE;
}
