Detailed Description

ONNX Runtime C API

Macro Definition Documentation

◆ ORT_API_VERSION

#define ORT_API_VERSION   21

The API version defined in this header.

This value is used by some API functions to behave as this version of the header expects.

Typedef Documentation

◆ ExecutionMode

◆ GraphOptimizationLevel

Graph optimization level.

Refer to https://www.onnxruntime.ai/docs/performance/graph-optimizations.html#graph-optimization-levels for an in-depth understanding of the Graph Optimization Levels.

◆ ONNXTensorElementDataType

Copied from TensorProto::DataType Currently, Ort doesn't support complex64, complex128

◆ ONNXType

typedef enum ONNXType ONNXType

◆ OrtAllocator

typedef struct OrtAllocator OrtAllocator

Memory allocation interface.

Structure of function pointers that defines a memory allocator. This can be created and filled in by the user for custom allocators.

When an allocator is passed to any function, be sure that the allocator object is not destroyed until the last allocated object using it is freed.

typedef void(* OrtThreadWorkerFn) (void *ort_worker_fn_param)

Thread work loop function.

Onnxruntime will provide the working loop on custom thread creation Argument is an onnxruntime built-in type which will be provided when thread pool calls OrtCustomCreateThreadFn

◆ OrtTrainingApi

◆ OrtTypeInfo

typedef struct OrtTypeInfo OrtTypeInfo

◆ OrtValue

typedef struct OrtValue OrtValue

◆ RegisterCustomOpsFn

typedef OrtStatus *( * RegisterCustomOpsFn) (OrtSessionOptions *options, const OrtApiBase *api)

Callback function for RunAsync.

Parameters
[in]user_dataUser specific data that passed back to the callback
