Enable simulated stream socket failures.
Defined in <SDL3_net/SDL_net.h>
void SDLNet_SimulateStreamPacketLoss(SDLNet_StreamSocket *sock, int percent_loss);| SDLNet_StreamSocket * | sock | The socket to set a failure rate on. |
| int | percent_loss | A number between 0 and 100. Higher means more failures. Zero to disable. |
Often times, testing a networked app on your development machine--which might have a wired connection to a fast, reliable network service--won't expose bugs that happen when networks intermittently fail in the real world, when the wifi is flakey and firewalls get in the way.
This function allows you to tell the library to pretend that some percentage of stream socket data transmission will fail.
Since stream sockets are reliable, failure in this case pretends that packets are getting lost on the network, making the stream retransmit to deal with it. To simulate this, the library will introduce some amount of delay before it sends or receives data on the socket. The higher the percentage, the more delay is introduced for bytes to make their way to their final destination. The library may also decide to drop connections at random, to simulate disasterous network conditions.
Setting this to zero (the default) will disable the simulation. Setting to 100 means everything fails unconditionally and no further data will get through (and perhaps your sockets eventually fail). At what percent the system merely borders on unusable is left as an exercise to the app developer.
This is intended for debugging purposes, to simulate real-world conditions that are various degrees of terrible. You probably should not call this in production code, where you'll likely see real failures anyhow.
It is safe to call this function from any thread.
This function is available since SDL_Net 3.0.0.
