This API allows external applications to link HyperMesh as a library and provides a limited set of functions and structures to access specific functionality.

There are several external files that are necessary, two header files (hm_extapi.h and optionally hm_extapi_error.h) that need to be included into the application, and a library file (hm_extapi.lib or libhm_extapi.so) that needs to be linked and provided with the application.
