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

SDLNet_AllocSocketSet

Allocate a socket set for use with SDLNet_CheckSockets().

Syntax

SDLNet_SocketSet SDLNet_AllocSocketSet(int maxsockets);

Function Parameters

maxsockets

the maximum amount of sockets to include in this set.

Return Value

Returns a socket set for up to maxsockets sockets, or NULL if the function ran out of memory.

Remarks

To query if new data is available on a socket, you use a "socket set" with SDLNet_CheckSockets(). A socket set is just a list of sockets behind the scenes; you allocate a set and then add/remove individual sockets to/from the set.

When done with a socket set, you can free it with SDLNet_FreeSocketSet.

Version

This function is available since SDL_net 2.0.0.
