The Microsoft Win32 Internet (WinInet) API provides stand-alone applications with easy access to standard Internet protocols such as Gopher, FTP, and HTTP. The WinInet API abstracts the protocols into a high- level interface that is familiar to Win32 developers.
The following is a list of error codes returned by the WinInet functions:
