# C API
|
|
|
|
**NOTE: The C API is PRE-RELEASE and subject to change.**
|
|
|
|
## Features
|
|
|
|
* Creating an InferenceSession from an on-disk model file and a set of SessionOptions.
|
|
* Registering customized loggers.
|
|
* Registering customized allocators.
|
|
* Registering predefined providers and set the priority order. ONNXRuntime has a set of predefined execution providers,like CUDA, MKLDNN. User can register providers to their InferenceSession. The order of registration indicates the preference order as well.
|
|
* Running a model with inputs. These inputs must be in CPU memory, not GPU. If the model has multiple outputs, user can specify which outputs they want.
|
|
* Converting an in-memory ONNX Tensor encoded in protobuf format, to a pointer that can be used as model input.
|
|
* Setting the thread pool size for each session.
|
|
* Dynamically loading custom ops.

## How to use it
|
|
|
|
1. Include [onnxruntime_c_api.h](/include/onnxruntime/core/session/onnxruntime_c_api.h).
|
|
2. Call ONNXRuntimeInitialize
|
|
3. Create Session: ONNXRuntimeCreateInferenceSession(env, model_uri, nullptr,...)
|
|
4. Create Tensor
|
|
1) ONNXRuntimeCreateAllocatorInfo
|
|
2) ONNXRuntimeCreateTensorWithDataAsONNXValue
|
|
5. ONNXRuntimeRunInference
