Function

Creates data of the aclfvFeatureInfo type for feature description. To destroy data of the aclfvFeatureInfo type, call aclfvDestroyFeatureInfo.

Atlas inference accelerator module: This API is not supported.

Prototype

aclfvFeatureInfo *aclfvCreateFeatureInfo(uint32_t id0, uint32_t id1, uint32_t offset, uint32_t featureLen, uint32_t featureCount, uint8_t *featureData, uint32_t featureDataLen)

Parameters

Parameter	Input/Output	Description
id0	Input	Repository 0 ID. Must be within [0, 1023]. Defaults to 0 in N:M mode. id0 and id1 together identify a repository.
id1	Input	Repository 1 ID. Must be within [0, 1023]. Defaults to 0 in N:M mode. id0 and id1 together identify a repository.
offset	Input	Offset of the first feature in the library. The offset value must be consistent with the number of features that have been added to the library. In N:M mode, the default value is 0.
featureLen	Input	Feature length, fixed at 36 bytes. The system verifies the length internally.
featureCount	Input	Number of features, up to 1 million in 1:N mode or up to 10 million in N:M mode.
featureData	Input	Pointers to feature values, which are stored contiguously based on the feature length. The first 4 bytes of each feature are 0.
featureDataLen	Input	Length of the memory allocated for the featureData pointer, used for verification.

Returns

Success: a pointer to data of the aclfvFeatureInfo type
Failure: nullptr
