Check the docs for SHGetFolderPath () with CSIDL_DESKTOPDI RECTORY. 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
SetCurrentDirec tory() 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.

Re: writing to text file

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,csPat h.GetBuffer(_MA X_PATH+1)) != 0) {
csPath.ReleaseB uffer();
CString csTempFile;
if(GetTempFileN ame(csPath,strP attern,0,csTemp File.GetBuffer( _MAX_PATH+1))
!= 0) {
csTempFile.Rele aseBuffer();
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()?
