New Revision: 32759
URL: http://svn.digium.com/view/asterisk?rev=32759&view=rev
Log:
revert my changes to convert fields of zt_pvt to use stringfields. When I did
this, I was not keeping in mind the fact that after a stringfield is overwritten
by another string, the memory used by the old string can not be recovered. I
would like to go back through these changes and make sure that stringfields are
not used for fields that are written to many times before these changes are
committed.
