#4353: [COMPATIBILITY BUG] inet_ntop NEEDS TO BE DEFINED on XP [solution inside]
---------------------------------------+-------------------------
Reporter: Gevalt | Owner:
Type: bug | Status: new
Priority: normal | Milestone: unspecified
Component: Engine: Networking | Version: 3.1.3
Operating System: Windows XP |
---------------------------------------+-------------------------
Trying to start Warzone 3.1.3 at XP SP3 computer causes error "missing
entry point for procedure inet_ntop in WS2_32.dll." This means the game
doesn't start at all.
The solution is extremely simple - define the inet_ntop function, as shown
in the link below.

/* cannot direclty use &size because of strict aliasing rules */
return (WSAAddressToString((struct sockaddr *)&ss, sizeof(ss), NULL,

dst : NULL;
}

''That's it. Link with ws2_32 library.''
Please build portable executable with this so I can test whenever it will
fix the issue for me.
Thanks in advance.
