FireFoot is library that provides an easy way for C language programmers to connect to Firebird database servers (and provably Interbase). It uses the Firebird/Interbase API.

Library supports:

• Create, delete, connect to Firebird database servers.
• Single transaction management.
• Common or parametrized SQL statement support.
• Support for basic data types and BLOBs.
• User management support.
• Support the backup and restore of databases.

This library exists as an alternative of Firebird/Interbase C language API. It is made in C language, using GLib object model.
It is planned to be multiplatform, working at least on Linux and Windows. Until now it is only tested on Linux, but shouldn't be a problem to port it to Windows.

FireFoot libary is released under the GNU/GPL version 2 licence.

Firebird is a relational database offering many ANSI SQL-92 features that runs on Linux, Windows, and a variety of Unix platforms. Firebird offers excellent concurrency, high performance, and powerful language support for stored procedures and triggers. It has been used in production systems, under a variety of names since 1981.
