C header files for various simulator titles' shared memory api, specifically for use in Linux programs

This project includes a daemon to handle all the telemetry mapping for external applications in the background, and the shared library for the external applications to use. The external application can either map and open the memory mapped filed directly (SIMAPI.DAT) and use the header file simapi.h to enumerate the fields within the data structure, or use the functions within simmapper.c to open and map the memory mapped file.

Building

To compile the shared library with the CMakeLists.txt in the root of the repo...

cmake -B build
cmake --build build

You will need sudo to install, which will place the library and public headers into /usr/local:

sudo cmake --install build
