Subject: Patch from Scott McKellar:
X-Git-Tag: osrf_rel_2_0_1~660
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=9b362feb87e3240305784bf86888629d1cb43655;p=OpenSRF.git

Patch from Scott McKellar:

This patch adds a new function so that code outside of osrf_hash.c
doesn't have to directly access the "current" member of an
osrfHashIterator.  This bit of encapsulation will make it easier
to refactor the osrfHash code.
