* Add _c versions of functions that otherwise return static buffersHarald Welte2019-04-101-0/+16
| | | | | | | | | | | | | | We have a habit of returning static buffers from some functions, particularly when generating some kind of string values. This is convenient in terms of memory management, but it comes at the expense of not being thread-safe, and not allowing for two calls of the related function within one printf() statement. Let's introduce _c suffix versions of those functions where the caller passes in a talloc context from which the output buffer shall be allocated. Change-Id: I8481c19b68ff67cfa22abb93c405ebcfcb0ab19b
* Add _buf() functions to bypass static string buffersHarald Welte2019-04-031-8/+19
| | | | | | | | | | | | | | | We have a number of static buffers in use in libosmo*. This means the related functions are not usable in a thread-safe way. While we so far don't have many multi-threaded programs in the osmocom universe, the static buffers also prevent us from calling the same e.g. string-ify function twice within a single printf() call. Let's make sure there's an alternative function in all those cases, where the user can pass in a caller-allocated buffer + size, and make the 'classic' function with the static buffer a wrapper around that _buf() variant.

* cosmetic apn: correct whitespace errorPhilipp Maier2018-12-071-1/+1
| | | | | | | there is a whitespace between the * and osmo_apn_to_str(). Lets remove this. Change-Id: I094e6eb08eacf2d6459c47a7370837601aa92925
* Fix/Update copyright notices; Add SPDX annotationHarald Welte2017-11-131-1/+21
| | | | | | | | Let's fix some erroneous/accidential references to wrong license, update copyright information where applicable and introduce a SPDX-License-Identifier to all files. Change-Id: I39af26c6aaaf5c926966391f6565fc5936be21af
* Make osmo_apn_to_str() more robustMax2017-10-201-0/+3
| | | | | | | Previously it would crash on NULL input. Let's handle it gracefully instead. Corresponding test case is also added. Change-Id: I587153e49d1c92128fac3ae5c124adba9592378e
* doxygen: unify use of \file across the boardNeels Hofmeyr2017-06-231-0/+2
| | | | | | | | | | | | | | | | | Considering the various styles and implications found in the sources, edit scores of files to follow the same API doc guidelines around the doxygen grouping and the \file tag. Many files now show a short description in the generated API doc that was so far only available as C comment. The guidelines and reasoning behind it is documented at https://osmocom.org/projects/cellular-infrastructure/wiki/Guidelines_for_API_documentation In some instances, remove file comments and add to the corresponding group instead, to be shared among several files (e.g. bitvec).

* gsm: Add APN conversion functionsJacob Erlbeck2016-01-151-0/+75
| | | | | | | | | | | | These functions are currently part of openbsc but also needed by other projects. The function have been renamed as follows: gprs_apn_to_str -> osmo_apn_to_str gprs_str_to_apn -> osmo_apn_from_str Sponsored-by: On-Waves ehf
* Add APN utility function to libosmogsmHarald Welte2015-05-251-0/+38
The current functions are used to 'qualify' an APN from the user-supplied APN name (name identifier) towards the fully-qualified APN name which is used in the .grps DNS zone.
