Open file in write mode problem

["André Pedralho" <apedralho gmail com>]

Hi all,
I'm trying to port an app with some file interactions. I used to use
only the stdio.h to open, read, write and close my text file, but now,
I want to do this using the gnome VFS.
Then, I've re-developed all the code, and I may open, read, write and
close the file using the gnome VFS. However, when I close my app and
run it again my file is erased by the gnome_vfs_open_uri(&handle,
uri, GNOME_VFS_OPEN_WRITE), I mean, all the content of my file is
erased.
Following there is a piece of my code:

    gchar *File = "/home/asp/test.txt";

    GnomeVFSHandle *handle;
    GnomeVFSURI *uri = gnome_vfs_uri_new(File);
    GnomeVFSResult result;
    if (!gnome_vfs_uri_exists(uri)) {
        g_print("Creating History file\n");
        if
(gnome_vfs_create_uri(&handle, uri, GNOME_VFS_OPEN_WRITE, 1,
0666)!=GNOME_VFS_OK) {
            g_print("Could not create a history file\n");
            return NS_ERROR_FAILURE;
        }
        gnome_vfs_close(handle);
    }

    if (gnome_vfs_open_uri(&handle, uri, GNOME_VFS_OPEN_WRITE)) {
        g_print("Could not open URI\n");
        return NS_ERROR_FAILURE;
    }

     GnomeVFSFileSize written;     
     gnome_vfs_write (handle, (gpointer)"some text", 9, &written);

     gnome_vfs_close(handle);

thanks in advance,
