Ref_BN

Extracts the main characteristics of the integer big number from the input structure.

Syntax

IppStatus ippsRef_BN(IppsBigNumSGN* pSgn, int* bitSize, Ipp32u** const ppData, const IppsBigNumState* pBN);

Include Files

ippcp.h

Parameters

pSgn	Pointer to the sign of IppsBigNumState *x.
bitSize	Length of the integer big number in bits.
ppData	Double pointer to the data array.
pBN	Integer big number of the context IppsBigNumState.

Description

The function extracts from the input structure the main characteristics of the integer big number: sign, length, and pointer to the data array. You can extract either the entire set or any subset of these characteristics. To turn off extraction of a particular characteristic, set the appropriate function parameter to NULL.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if any of the specified pointers is NULL.
ippStsContextMatchErr	Indicates an error condition if the context parameter does not match the operation.
