A Portable General-Purpose Application Programming Interface for Cif 2.0

The CIF API is an application programming interface and accompanying reference implementation for reading and writing CIFs and manipulating CIF data, with support for all versions of CIF through CIF 2.0. It features full support for Unicode in data block and save frame codes, data names, and data values; flexible character encoding; CIF 2.0 List and Table data types; CIF version auto-detection; event-based parsing; and arbitrary-precision numeric values. The interface and implementation are written in portable C, and they have been successfully built and tested on Linux, OS X and Windows. The CIFAPI is open-source software, available for use under the GNU Lesser General Public License.
