(This function is part of SDL_net, a separate library from SDL.)


Initialize the SDL_net library.

Header File

Defined in <SDL3_net/SDL_net.h>


int SDLNet_Init(void);

Return Value

(int) Returns 0 on success, -1 on error; call SDL_GetError() for details.


This must be successfully called once before (almost) any other SDL_net function can be used.

It is safe to call this multiple times; the library will only initialize once, and won't deinitialize until SDLNet_Quit() has been called a matching number of times. Extra attempts to init report success.

Thread Safety

It is safe to call this function from any thread.


This function is available since SDL_net 3.0.0.
