From 9297e1950f76270e99c76970f57810e01e305a3b Mon Sep 17 00:00:00 2001 From: ShyamsundarR Date: Mon, 30 Jul 2018 20:16:21 -0400 Subject: contrib: Remove gf_mkostemp copied from GLibC gf_mkostemp is borrowed from GLibC a long time back, we now have mkostemp or mkstemp alternatives with all distributions and versions that we care for. As a result removing this from the contrib directory and modifying the one instance that is still using the same. This is part of code cleanup as we cleaned up coverity SECUR_TEMP errors.
