Performs a lookup of a hostname and returns its IP address. If the lookup fails the function returns a blank string.

You must first call WSAStartup() to initialize the Winsock DLL prior to doing the lookup, and call WSACleanup() when operations are complete.

This will convert a HSV value into an RGB DWORD. There is an example which will draw a box with given HSV values.

The hsv2dword function takes the 3 components as floats as described by the remark preceding the function.
