From dae39843f478d181da5b5e1c2c703dfcaaf838c1 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Thu, 17 Jul 2008 17:16:47 +0200 Subject: [S390] cio: Export chsc_error_from_response(). Make chsc_error_from_response() available to chsc callers outside of chsc.c (namely qdio) to avoid duplicating error checking code.
