Function

Obtains the memory address and memory size of the operator binary data on a device.

Prototype

aclError aclrtBinaryGetDevAddress(const aclrtBinHandle binHandle, void **binAddr, size_t *binSize)

Parameters

Parameter	Input/Output	Description
binHandle	Input	Operator binary handle. For details about the type definition, see aclrtBinHandle. Call aclrtBinaryLoadFromFile or aclrtBinaryLoadFromData to obtain the operator binary handle and pass it as an input parameter.
binAddr	Output	Memory address of the operator binary data on a device. If lazy loading is set (by setting aclrtBinaryLoadOptions.aclrtBinaryLoadOption.aclrtBinaryLoadOptionValue.isLazyLoad to 1) for operator binary data loading, the binAddr obtained by calling this API is a null pointer.
binSize	Output	Size of the operator binary data, in bytes.

Parameter

Input/Output

Description

binHandle

Input

Operator binary handle. For details about the type definition, see aclrtBinHandle.

Call aclrtBinaryLoadFromFile or aclrtBinaryLoadFromData to obtain the operator binary handle and pass it as an input parameter.

binAddr

Output

Memory address of the operator binary data on a device.

If lazy loading is set (by setting aclrtBinaryLoadOptions.aclrtBinaryLoadOption.aclrtBinaryLoadOptionValue.isLazyLoad to 1) for operator binary data loading, the binAddr obtained by calling this API is a null pointer.

binSize

Output

Size of the operator binary data, in bytes.

Returns

0 on success; otherwise, failure. For details, see aclError.
