The following functions are implemented in the WS2_32.DLL, and are intended to be used by applications that install Windows Sockets transport and name space service providers on a machine. These functions neither affect currently running applications, nor are the changes made by these functions visible to currently running applications.
For all providers, a provider ID is a GUID which is generated by the developer of the provider (using the UUIDGEN.EXE utility) and supplied to WS2_32.DLL.
