I have a mapped path and I want to get the actual network path that it
refers to. For example, if I have
"Z:\"
I want to see that it connects to:
"\\some_server\Test"

So I'm using the poorly documented WNetGetUniversalName function and it
fails every damn time I use it. The function returns a success, but
the output information is bad. In a couple examples of source I
expanded my output string and found that the first 4 characters are
garbage but the following characters represent the string that I
expect. What's the deal with that? I have XP Pro-SP2

Read the doc carefully. On successfull return,the buffer passed as the third
parameter will not be filled with a string but a structure that containes a
string. So what you call "garbage" is a pointer to the universal name. You
have to follow that pointer to find the actual name:

char buffer[1024];
DWORD size = sizeof(buffer);
WNetGetUniversalName(_T("s:\\TestConsole"),
UNIVERSAL_NAME_INFO_LEVEL, buffer, &size);
_putts(((UNIVERSAL_NAME_INFO*) buffer)->lpUniversalName);
