PolyGFSub

Subtracts one polynomial from another.

Syntax

IppStatus ippsPolyGFSub_8u(const IppsPoly_GF8u* pSrcA, const IppsPoly_GF8u* pSrcB, IppsPoly_GF8u* pDstR);

pSrcA	Pointer to the first (minued) polynomial.
pSrcB	Pointer to the second (subtrahend) polynomial.
pDstR	Pointer to the resulting polynomial.

This function is declared in the ippdi.h file. The function performs polynomial subtraction.

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 any of the specified contexts is not valid.
ippStsOutOfRangeErr	Indicates an error condition if maxDegree (pDstR) < max(degree( pSrcA), degree(pSrcB)), where degree is the actual degree and maxDegree is the highest possible degree specified in the respective polynomial context.
