No, that list is not correct.
1) select() can *only* be used on a socket in Windows, and it puts its
error info in WSAGetLastError().
2) ioctl() should *not* be used on sockets. Instead, ioctlsocket()
shuold be used. ioctlsocket() puts its error info in WSAGetLastError().
(http://msdn.microsoft.com/library/psdk/winsock/ovrvw3_98mq.htm). (loads
fine in my Netscape, doesn't look all that good, but definitly readable)
3) fcntl() should *not* be used on sockets. ioctlsocket() again.
Generaelly, all functions dealing with sockets use WSAGetLastError().
And sockets and file descriptors are *not* necessarily interchangable on
Win32.
Note - this is Win32, *not* cygwin. Cygwin maps to errno, AFAIK.
