Subject: Changed rc_dfl_resolve to initlize the private data, instead of rc_initalize
X-Git-Tag: krb5-1.0-alpha4~5
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=d54f7c390304abba83886234e2ee03d35b2f07b0;p=krb5.git

Changed rc_dfl_resolve to initlize the private data, instead of rc_initalize
or rc_recover.  This means that caller must call rc_close after
calling rc_dfl_resolve.  This change was required in order to prevent
a memory leak in rc_dfl_resolve, since it was doing some memory allocation
already; it now does all necessary memory allocation, and rc_close
frees all of the memory used by rc_dfl_resolve.
