Re: [xml] xmlSaveToFd problem

[Torbert, Barton]

I get further now, but still having problems.  Here is my code snippet

.
.
.
xmlSaveCtxtPtr ctxt;

   int fd;
   fd = open ((char*)"c:\\temp\\test.xml", O_RDWR | O_CREAT);
   ctxt = xmlSaveToFd (fd, "UTF-8", 1);
  // ctxt = xmlSaveToFilename ((char *)"c:\\temp\\test.xml", "UTF-8",1);

   long ll;
   
   ll = xmlSaveDoc (ctxt, doc);
   xmlSaveClose(ctxt);
  close (fd);
   
   /*free the document */
   xmlFreeDoc(doc);
.
.
.
If I use the xmlSaveToFilename call I get the output in the file I
expect.
If I open the file to create the file descriptor (fd), the xmlSaveDoc
returns the success value of 0, but the file is empty.  Is there some
options flags I need to set in the open command so the library can write
to the file.
For what it is worth I am running my tests on Windows XP using Visual
Studio .NET 2003.

  there is no xmlSave.h, but xmlsave.h

  Either your compiler is buggy or you tried to dereference a pointer to
the
structure. You can't.

  Any normal C compiler can use pointer to undefined structs

  ctxt = xmlSaveToFd(...)
