[pygtk] gnomevfs and access rights

[Mystilleef]

Hello,

Most I/O libraries have functions that determine whether
users have access rights or permissions to a particular
file. The GNOME-VFS Python binding seems to have some for
permissions but I have not found any for access rights.

In particular, I'm looking for

	gnomevfs.PERM_ACCESS_READABLE
	gnomevfs.PERM_ACCESS_WRITABLE
	
or their equivalent. These fields seem to be present in the
GNOME-VFS C binding, at least according to the documenation.

Thanks
