[libvirt] [PATCH 1/2] Remove uid param from directory lookup APIs
Daniel P. Berrange
berrange at redhat.com
Thu May 24 13:44:32 UTC 2012
From: "Daniel P. Berrange" <berrange at redhat.com>
Remove the uid param from virGetUserConfigDirectory,
virGetUserCacheDirectory, virGetUserRuntimeDirectory,
and virGetUserDirectory
These functions were universally called with the
results of getuid() or geteuid(). To make it practical
to port to Win32, remove the uid parameter and hardcode
geteuid()
