C API of Inference Engine bridge unlocks using of OpenVINO Inference Engine library and all its plugins in native applications disabling usage of C++ API. The scope of API covers significant part of C++ API and includes an ability to read model from the disk, modify input and output information to correspond their runtime representation like data types or nmemory layout, load in-memory model to Inference Engine on different devices including heterogeneous and multi-device modes, manage memory where input and output is allocated and manage inference flow:
