libsmpp34 - C library for SMPP 3.4

This repository contains a C-language library implementing the SMPP Protocol version 3.4 as specified by the SMPP Developers Forum.

The library was inherited from the c-open-smmp34 project, which unfortunately doesn't have any form of revision control system and hence the Osmocom Open Source Mobile Communications project has imported the v1.10 release into this git repository and performed subsequent improvements.


The official homepage of the Osmocom version of the library is http://osmocom.org/projects/libsmpp34 while the original upstream project is found at https://sourceforge.net/projects/c-open-smpp-34/

GIT Repository

You can clone from the Osmocom libsmpp34.git repository using

git clone git://git.osmocom.org/libsmpp34.git

There is a cgit interface at http://git.osmocom.org/libsmpp34/


API documentation is generated during the build process, but also available online from the upstream project at http://c-open-smpp-34.sourceforge.net/out-1.10/web/c-open-libsmpp34_en/index.html
