From: miker Date: Thu, 31 May 2007 12:12:02 +0000 (+0000) Subject: Patch from Scott McKellar; Adds calls to strerror() where appropriate in X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=1b33fe9774a6d3c42c8b0f285993ebd14caa0f3e;p=opensrf%2Fbjwebb.git Patch from Scott McKellar; Adds calls to strerror() where appropriate in OpenSRF/src/utils/socket_bundle.c. Applied with some additional changes to clean up log messages and correct an instance of printf'ing a getpid as an int instead of a long. http://list.georgialibraries.org/pipermail/open-ils-dev/2007-May/001148.html git-svn-id: svn://svn.open-ils.org/OpenSRF/trunk@930 9efc2488-bf62-4759-914b-345cdb29e865 --- diff --git a/src/utils/socket_bundle.c b/src/utils/socket_bundle.c index 66a7e83..5247328 100644 --- a/src/utils/socket_bundle.c +++ b/src/utils/socket_bundle.c @@ -72,10 +72,11 @@ int socket_open_tcp_server(socket_manager* mgr, int port, char* listen_ip) { int sock_fd;
