Or use existing tools like Process Explorer OK, tried that. After saving files to a Temp folder on the flash drive mounted as E:, process explorer show that the app has 3 files on it: FileE:\ FileE:\ FileE:\Temp Think this is worth a Bugzilla report against GtkFileChooserDialog?

Grab Process Explorer and use it's Find Handle or DLL function and just search for the drive letter - that should tell you what has the flash drive open. -- < Jernej Simončič ><><><><>< http://eternallybored.org/ > ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

Hi Ian, On Tue, 23 Mar 2010 18:08:05 -0700 you wrote: > So only stdin/out/err are open and the cwd is not on the flash drive. > What the heck else could be preventing Windows from un-mounting it? Sadly it's probably some deep buried magic in Windows. The earlier post about working directories was on the right lines, I suspect, except it's not the application working directory that's the problem but some internal cache record. I've seen this happen with Windows Exploder - after browsing the flash drive it's sometimes not enough to browse away and you need to close that explorer window to allow the safe removal. You could try (though it's unlikely to help) explicitly setting the file chooser's current directory to C:\ before you delete it. ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

> fd 0 is open !! > fd 1 is open !! > fd 2 is open !! That is a rather pointless exercise as "file descriptors" on Windows aren't an operating system concept, as on Unix. In C code on Windows, "file descriptors" are just indexes into tables in the C library. There might even be several different C libraries (with overlapping but unrelated file descriptor values) in use by a process at any time. (That is, one C library, say msvcrt.dll, used by the main .exe, another, say msvcr80.dll, used by one DLL, and a third DLL might be using a static C library. Etc.) Files opened with operating system calls don't have any file descriptors. To see what files actually are open by a Windows process, you need to use Windows-specific code. Or use existing tools like Process Explorer from http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx . --tml ___ gtk-list mailing list gtk-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-list

I'm using GTK > 2.16.6. I tried a hack to temporarily remove the call to the GtkFileChooserDialog and where it was calling gtk_file_chooser_get_current_folder I replaced that with a static string giving the path to the last drive. With this, after the export Windows could un-mount the flash drive just fine without closing the program. So this tells me that the problem does seem to be with the GtkFileChooserDialog. Then (with the file chooser back in) as well as code to g_print the output of getcwd, I added a loop calling fstat on all file descriptors from 0 to 0x with a g_print of those that return success (i.e. are open) and it printed this: CWD: 'C:\SLRC\2010\Results\r6-GS-sq' fd 0 is open !! fd 1 is open !! fd 2 is open !! So only stdin/out/err are open and the cwd is not on the flash drive. What the heck else could be preventing Windows from un-mounting it?

Try using chdir to change to some other drive after you're done. Thanks but that doesn't seem to be the problem. The program is accessing files in its working directory, and after the export it can go on accessing them still which means the working directory did not change. But to be doubly-sure I just added a call to getcwd() after the export and g_printed the result and it shows the expected directory, not the flash drive.
