I have a Hash of Hashes in an object. It's accessed through access routines, but I'm trying to pull a hash out of it via a key (pathnames pointing to logical volume info). However, when the access routine returns the value, it's returning the dereferenced HASH, not the pointer to the hash. However if I put a \ in front of the hash in the access routine, then the calling routine gets "not a hash ref". I.e. Access routine is returning
$p->{hashname}{'path'}=<another hashref>;
But that has is being expanded -- in the debugger it says it is being returned in a scalar context. How can I annotate the 'another hash' so it gets returned as a reference? I know how too force it into scalar context, but I need to force it into staying as a reference...I'm sure this is a simple perl-101 question, but I'm just missing a big enough cluestick! ;-(
Anyone wanna hit me over the head w/one?... ;-)
Thanks!
(some days I have to look at my license to remember my name!)
