The Met Office has annouced it is moving to a new platform called "Datahub" that uses a different style API than Datapoint. This repo has therefore been archived.
https://www.metoffice.gov.uk/services/data/datapoint/notifications/weather-datahub
A C++ Library for accessing weather data via the Met Office's open data API known as DataPoint. Depends on cURL and rapidJSON.
Designed to make few calls to the Datapoint API as possible, in order to keep within the fair use policy and improve the general speed of the library. Thus some functions like 'val/wxfcs/all/json/capabilities' are avoided.

This module is in no way part of the DataPoint project/service. No support for this module is provided by the Met Office and may break as the DataPoint service grows/evolves.
Datapoint for C++ example program and library code requires libcurl and rapidJSON to compile.
