Ref_BN

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

Syntax

IppStatus ippsRef_BN(IppsBigNumSGN *sgn, int *bitSize, const Ipp32u **pData, const IppsBigNumState *x);

Parameters

sgn	Sign of IppsBigNumState *x.
bitSize	Length of the integer big number in bits.
pData	Pointer to the data array.
x	Integer big number of the context IppsBigNumState.

Description

This function is declared in the ippcp.h file. 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.
