From: Greg Hudson Date: Mon, 1 Nov 2010 15:19:00 +0000 (+0000) Subject: krb5_get_error_message cannot return NULL, and returns "Success" on X-Git-Tag: krb5-1.10-alpha1~669 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=7143f3daeaebca9839771ee36bf7b4ee1d11a3ac;p=krb5.git krb5_get_error_message cannot return NULL, and returns "Success" on error code 0. Simplify some overly paranoid code accordingly. git-svn-id: svn://anonsvn.mit.edu/krb5/trunk@24489 dc483132-0cff-0310-8789-dd5450dbe970 --- diff --git a/src/kadmin/dbutil/dump.c b/src/kadmin/dbutil/dump.c index caff137a4..0e1b60959 100644 --- a/src/kadmin/dbutil/dump.c +++ b/src/kadmin/dbutil/dump.c @@ -2514,18 +2514,8 @@ load_db(argc, argv) if((kret = krb5_db_create(kcontext, db5util_db_args))) { const char *emsg = krb5_get_error_message(kcontext, kret);
