The Windows Sockets SPI uses the following function prefix naming convention.
| Prefix | Meaning | Description |
|---|---|---|
| WSP | Windows Sockets Service Provider | Transport service provider entry points |
| WPU | Windows Sockets Provider Upcall | Ws2_32.dll entry points for service providers |
| WSC | Windows Sockets Configuration | WS2_32.dll entry points for installation applets |

As described above, these entry points are not exported (with the exception of WSPStartup and NSPStartup), but are accessed through an exchange of dispatch tables.
