#248 closed Bug report

CAsyncSocketEx::IOCtl() returns wrong result

Description

The return value of CAsyncSocketEx::IOCtl() should be
inverted.
CAsyncSocketEx::IOCtl() calls ioctlsocket() which
returns 0 if success, and SOCKET_ERROR if not
success.

CAsyncSocketEx::IOCtl() therefore should return TRUE
if ioctlsocket() returns 0. This is not the case at the
moment.
This causes problems in WindowProc() of
AsyncSocketEx.cpp when processing the FD_READ
event.

A correct implementation of IOCtl() would be:

BOOL CAsyncSocketEx::IOCtl( long lCommand,
DWORD* lpArgument )
{

return (SOCKET_ERROR != ioctlsocket

(m_SocketData.hSocket, lCommand, lpArgument));
}
