Errorcodes are [[constant]]s that get generated by a [[function]] or another piece of code, when there occurs a malfunction.
For example when you try the following code with the [[Network_DLL|Network.DLL]] function [[NET_Connect]]():
<pre>
if( (netid = NET_Connect("some-not-existing-server",1234)) < 0 )
//error
else
//success
end
</pre>
The code [[NET Errorcodes|NET_ERROR_CONNECTING]] is returned, which in fact is the value -20, which is less than 0, so we go into the //error section. Here we can for example output the error:
<pre>
say("Error: " + NET_GetError(netid));
</pre>
Or perform an action based on the type of error:
<pre>
switch(netid)
case NET_ERROR_CONNECTING:
say("Could not connect to the specified server.");
end
case NET_ERROR_TOOMANYCONNS:
say("There are too many connections open at this point.");
end
end

</pre>

Note that errorcodes do not necessarily have to be negative numbers; Network.DLL does this so the check of an error is just the check if the returned value is negative.

Below is a list of errorcodes generated by [[:Category:dll|DLL's]] and others.
