From: E. Scott Daniels Date: Thu, 13 Aug 2020 19:12:35 +0000 (-0400) Subject: Correct potential leaks in xapp class. X-Git-Tag: 2.3.1~2 X-Git-Url: https://gerrit.o-ran-sc.org/r/gitweb?a=commitdiff_plain;ds=inline;h=refs%2Fchanges%2F46%2F4546%2F2;p=ric-plt%2Fxapp-frame-cpp.git Correct potential leaks in xapp class. Sonar identified some potential memory leaks in the run function of the xapp class. This change addresses those issues, and ensures that the unused parameter grumblings which were attempted to be corrected in the last change are also addressed. Issue-ID: RIC-629 Signed-off-by: E.
