Parameters

ppElmA: Pointer to the array of contexts of the finite field elements representing the base of the exponentiation.
ppE: Pointer to the array of the Big Number contexts storing the exponents.
nItems: Number of exponents.
pElemR: Pointer to the context of the resulting element of the finite field.
pGFp: Pointer to the context of the finite field.
pScratchBuffer: Pointer to the scratch buffer.

Description

This function multiplies exponents of elements of the finite field. The finite field is specified by the context

pGFp

. You can get the size of the scratch buffer by calling the

ippsGFpScratchBufferSize

function.

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 any of the context parameters IppsGFpState, IppsBigNumState, and IppsGFpElement does not match the operation.
ippStsOutOfRangeErr: Indicates an error condition if any of the elements of
ppElmA
do not belong to the finite field specified by the context
pGFp
.
ippStsBadArgErr: Indicates an error condition if
nItems
is less than 1 or greater than 6.
