The YEI 3-Space Sensor Application Programming Interface (API) is a series of functions, classes, and structure definitions designed to make writing applications that utilize the YEI 3-Space family of sensors fast and easy to support. The C/C++ variant of the API is built as a header (.h) and dynamic link library (.dll + .lib). With the C/C++ API, users that require easy integration of the 3-Space family of sensors into programming environments not natively supported may import the dynamic link library and call its contained functions from the importing program, as the API's function prototypes are all compiled as C prototypes and are name mangled as such.
