Global Functions¶
IEStatusCode ie_blob_make_memory(
const tensor_desc_t* tensorDesc,
ie_blob_t** blob
)
Creates a blob with the specified dimensions, layout and to allocate memory.
Parameters:
tensorDesc |
Tensor descriptor for Blob creation. |
blob |
A pointer to the newly created blob. |
Returns:
Status code of the operation: OK(0) for success.
IEStatusCode ie_blob_make_memory_from_preallocated(
const tensor_desc_t* tensorDesc,
void* ptr,
size_t size,
ie_blob_t** blob
)
Creates a blob with the given tensor descriptor from the pointer to the pre-allocated memory.
Parameters:
tensorDesc |
Tensor descriptor for Blob creation. |
ptr |
Pointer to the pre-allocated memory. |
size |
Length of the pre-allocated array. |
blob |
A pointer to the newly created blob. |
Returns:
Status code of the operation: OK(0) for success.
Creates a blob describing given roi_t instance based on the given blob with pre-allocated memory.
Parameters:
inputBlob |
original blob with pre-allocated memory. |
roi |
A roi_tinstance inside of the original blob. |
blob |
A pointer to the newly created blob. |
Returns:
Status code of the operation: OK(0) for success.
