Check the docs for SHGetFolderPath() with CSIDL_DESKTOPDIRECTORY. That will
get you the fully qualified path to the desktop folder. Use that to create a
file name.

You have a number of options to create a file name. For example, can use
SetCurrentDirectory() and then GetTempFileName() or _splitpath() and
_makepath().

Once you have a file name, you can create it however you like -
CreateFile(), fopen(), CFile class etc.

For the most part if you are writing Windows programs I'd use CreateFile,
ReadFile, and WriteFile (or the Ex versions). I just wrote this routine
yesterday (uses MFC sorry) to create a temp file name:

CString GetTempFilePath(LPCTSTR strPattern)
{
CString csPath;
if(GetTempPath(_MAX_PATH,csPath.GetBuffer(_MAX_PATH+1)) != 0) {
csPath.ReleaseBuffer();
CString csTempFile;
if(GetTempFileName(csPath,strPattern,0,csTempFile.GetBuffer(_MAX_PATH+1))
!= 0) {
csTempFile.ReleaseBuffer();
return csTempFile;
}
}
return CString();
}

Using the functions that Will is referring to. It works pretty well
actually.

Which one?

Did you try to diagnose the problem looking at errno or strerror()?
