LPWSTR = wchar_t*

LPCWSTR = const wchar_t*

You can see the actual declarations for yourself in wtypes.h

Use GetCommandLineW() (notice the W) to get the command line as a Unicode
string (or use GetCommandLineA() and then call MultiByteToWideChar()), and
then pass the string to CommandLineToArgvW().  It will return an allocated
array of Unicode strings and the number of entries in the array.  You can
then loop through the array converting the Unicode strings to ANSI strings
as needed.  For example:

    int my_argc = 0;
    LPWSTR* my_argv = CommandLineToArgvW(GetCommandLineW(), &my_argc);
    if( NULL != my_argv )
    {
        for(int i = 0; i < my_argc; ++i)
            // use my_argv[i] as needed...

        GlobalFree(my_argv);
    }

BTW, CommandLineToArgvW() is not available on Win9x/ME at all.  If you need
a solution that works across OS versions, then you will just have to parse
the command line manually, or use the VCL's ParamCount() and ParamStr()
functions.
