GFPow

Raises an element of a finite field to a power.

Syntax

IppStatus ippsGFPow_8u(Ipp8u gfeA, int pow, Ipp8u* pR, const IppsGFSpec_8u* pGF);

Parameters

gfeA	The element of the finite field to be exponentiated.
pow	The exponent.
pR	Pointer to the result of exponentiation.
pGF	Pointer to the context of the finite field.

Description

This function is declared in the ippdi.h file. The function performs exponentiation over the finite field. The following pseudocode represents this function, provided gfeR is the result of the operation:

gfeR = gfeA^pow.

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 pointed by pGF is not valid.
ippStsRangeErr	Indicates an error condition if gfeA is not a valid element of the finite field.
