Net*() and Win 95/98

If you got here, you probably want to use the Net*() API group on Windows 95 or Windows 98. Most likely, you already tried that, and it didn't work. Here are a few tips:

On Win9X, you need to include svrapi.h, not lm.h. Also, you do not link against netapi32.lib and netapi32.dll; you use svrapi.lib/svrapi.dll instead. If you have to support both NT and Win9X in one program, your best bet is to load the appropriate DLL dynamically at run-time.

Note that the Net*() functions have different calling sequences and semantics, as compared to the NT versions. In particular, all strings are ANSI; not all info levels are available; and instead of having the API allocate a buffer which you have to free, you need to reserve enough buffer space:

    // Windows NT
    BYTE *buf;
    DWORD prefmaxlen;
    // ...
    buf = NULL;
    prefmaxlen = 8192; // or whatever
    result = NetSomeFunction( ..., &buf, prefmaxlen, ... );
    // process buffer ...
    NetApiBufferFree( buf );

    // Windows 9X
    BYTE *buf;
    WORD cbBuffer;
    // ...
    cbBuffer = 8192; // or whatever
    buf = (BYTE *) malloc( cbBuffer );
    result = NetSomeFunction( ..., buf, cbBuffer ... );
    // process buffer ...
    free( buf );
