B.1 Introduction

A Windows Sockets implementation must implement ALL the functionality described in the Windows Sockets documentation. Validation of compliance is discussed in section B.8.

Windows Sockets Version 1.1 implementations must support both TCP and UDP type sockets. An implementation may support raw sockets (of type SOCK_RAW), but their use is deprecated.

Certain APIs documented above have special notes for Windows Sockets implementors. A Windows Sockets implementation should pay special attention to conforming to the API as documented. The Special Notes are provided for assistance and clarification.
