Detailed Description

An extension for public Blob API allowing to create blobs in uniform manner.

Function Documentation

blob_copy()

void InferenceEngine::blob_copy	(	Blob::Ptr	src,
		Blob::Ptr	dst
	)

Copies data with taking into account layout and precision params.

Parameters

[in]	src	The source Blob::Ptr
[in]	dst	The destination Blob::Ptr

CopyVectorToBlob()

template<typename T >

void CopyVectorToBlob	(	const InferenceEngine::Blob::Ptr	outputBlob,
		const std::vector< T > &	inputVector
	)

Copy data from std::vector to Blob.

Template Parameters

T	type of data in std::vector

Parameters

outputBlob	An output blob to copy to
inputVector	An input std::vector to copy from

ie_memcpy()

int ie_memcpy	(	void *	dest,
		size_t	destsz,
		void const *	src,
		size_t	count
	)

Copies bytes between buffers with security enhancements Copies count bytes from src to dest. If the source and destination overlap, the behavior is undefined.

Parameters

dest	A Pointer to the object to copy to
destsz	A max number of bytes to modify in the destination (typically the size of the destination object)
src	A pointer to the object to copy from
count	A number of bytes to copy

Returns

zero on success and non-zero value on error.
