A future patch needs to look up pw_gid; but it is wasteful to crawl through getpwuid_r twice for two separate pieces of information, and annoying to copy that much boilerplate code for doing the crawl. The current internal-only virGetUserEnt is also a rather awkward interface; it's easier to just design it to let callers request multiple pieces of data as needed from one traversal. And while at it, I noticed that virGetXDGDirectory could deref NULL if the getpwuid_r lookup fails. * src/util/virutil.c (virGetUserEnt): Alter signature. (virGetUserDirectory, virGetXDGDirectory, virGetUserName): Adjust callers. Signed-off-by: NEric Blake <eblake@redhat.com>
