Syntax

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

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.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
