This library is not updated for InfluxDB 0.9.0. There are breaking changes to the API, use at your own risk.
We encourage you to submit a pull request if you have a contribution. If you make a PR please explicitly call @beckettsean to get eyes on your PR.
A C89 library to play with the REST API of an InfluxDB database.
This implementation is meant as a C rewrite of the influxdb-go package.

./test3Requirements:
- A compiler supporting C89 (tested with GCC 4.8.2 and Clang 3.3);
- Autotools & libtool;
- libcurl;
- libjson;
Steps to build and install the library:
./bootstrap
./configure
make
sudo make installThat will install the libinfluxdb.so into /usr/local/lib/ and headers into /usr/local/include/influxdb/.
Generate documentation with:
make docsThen, you will find HTML and LaTeX in docs directory.
