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

Remove a socket from a set of sockets to be checked for available data.

== Syntax ==

<syntaxhighlight lang='c'>
int SDLNet_DelSocket(SDLNet_SocketSet set, SDLNet_GenericSocket sock);
</syntaxhighlight>

== Function Parameters ==

{|
|'''set'''
|the socket set to remove a socket from.
|-
|'''sock'''
|the socket to remove from the set.
|}

== Return Value ==

Returns the total number of sockets contained in the set (after
<code>sock</code>'s removal), or -1 if <code>sock</code> was not in the
set.

== Remarks ==

Generally you don't want to call this generic function, but rather the
specific, inline function that wraps it: [[SDLNet_TCP_DelSocket]]() or
[[SDLNet_UDP_DelSocket]]().

If <code>sock</code> is NULL, nothing is removed from the set; this lets
you query the number of sockets currently contained in the set.

This will return -1 if the socket was not found in the set; in such a case,
nothing is removed from the set.

== Version ==

This function is available since SDL_net 2.0.0.
