add to osmo_sock_get_name*() API Basically, I am applying code review that I would have given had I not been on vacation when the last osmo_sock_get_name* stuff was merged. osmo_sock_get_name2() is so far a static internal function. However, it is nothing like osmo_sock_get_name(), so instead rename it to osmo_sock_get_ip_and_port(). Also make it public API, no need to hide it. I'm adding an "and" in the name to hopefully clarify: "ip_port" vs. "ip_and_port" -- there already are _get_X_ip_port() functions that only return the port string, despite "ip" in the name. Add new public osmo_sock_get_name2(), which is like osmo_sock_get_name(), except it uses a static string instead of talloc, and omits the braces. This is most convenient for log statement formats, avoiding dyn allocations. Add new osmo_sock_get_name_buf(), which is like osmo_sock_get_name2() but writes to a caller provided char buffer. Use osmo_sock_get_name_buf() in the implementation of osmo_sock_get_name(), but use another (non-static) local string buffer, because adding braces is too complex without talloc_snprintf(). Rationale: I want to improve the logging of socket errors, e.g. change DLMGCP ERROR Failed to read: 111/Connection refused (mgcp_client.c:720) to DLMGCP ERROR Failed to read: r=10.0.99.2:2427<->l=10.0.99.2:2728: 111='Connection refused' (mgcp_client.c:721) but it is just not handy to compose logging with the current API: - osmo_sock_get_name() requires a talloc_free(). - all the others require output buffers. - the only way to conveniently compose a logging string and, - notably, the only trivial way to skip the string composition if the logging level is currently muted, is to have a function that returns a static string: the new osmo_sock_get_name2(). - (I think the osmo_sock_get_{local,remote}_* convenience wrappers should never have been added, because they encourage the caller to invoke the same code twice, for IP addr and port, and throw away one half each time.)

This repository contains a set of C-language libraries that form the core infrastructure of many Osmocom Open Source Mobile Communications projects.
Historically, a lot of this code was developed as part of the OpenBSC project, but which are of a more generic nature and thus useful to (at least) other programs that we develop in the sphere of Free Software / Open Source mobile communications.
There is no clear scope of it. We simply move all shared code between the various Osmocom projects in this library to avoid code duplication.
The libosmcoore.git repository build multiple libraries:
The official homepage of the project is https://osmocom.org/projects/libosmocore/wiki/Libosmocore
You can clone from the official libosmocore.git repository using
git clone git://git.osmocom.org/libosmocore.git
There is a cgit interface at http://git.osmocom.org/libosmocore/
Doxygen-generated API documentation is generated during the build process, but also available online for each of the sub-libraries at http://ftp.osmocom.org/api/latest/libosmocore/
Discussions related to libosmocore are happening on the openbsc@lists.osmocom.org mailing list, please see https://lists.osmocom.org/mailman/listinfo/openbsc for subscription options and the list archive.
