UNICODE to ANSI

I have a win32 app in which all strings and chars are defined as UNICODE.  Within the app, there exist a number of winsock calls.  When I pass a UNICODE string to a winsock function, the winsock function fails.  I thought I read somewhere that NT will automatically convert a string to ANSII if that is required by the function.  Apparently it is not working in this case.  Can someone tell me or show me of an easy way to convert from UNICODE to ANSII?
Thanks.

There is no "automatic" UNICODE to ANSI.  You must check the function call's requirements (sometimes VERY carefully as documentation is inconsistent) and pass either a UNICODE or ANSI string based on what it is expecting.  There are a few options:

1) The MFC header file AFXPRIV.H includes a definition of a macro called W2A that will take a LPCWSTR and return a LPSTR.  

2) You can call the wcstombs to convert from UNICODE to ASNI from the C runtime library.

3) You can write your own.  Just pick out every other byte until you get a NULL and return that value.
