GFPXQNeg

Computes the additive inverse for an element of the GF(p^d^2) field.

Syntax

IppStatus ippsGFPXQNeg(const IppsGFPXQElement *pGFpxqElementA, IppsGFPXQElement *pGFpxqElementR, IppsGFPXQState *pGFpxq);

Parameters

pGFpxqElementA	Pointer to the context of the given GF(`p^d^2`) element.
pGFpxqElementR	Pointer to the context of the resulting GF(`p^d^2`) element.
pGFpxq	Pointer to the context of the GF(`p^d^2`) field.

Description

This function is declared in the ippcp.h file. The function computes the additive inverse for a given element of the GF(p^d^2) field. The following pseudocode represents this operation: R = 0 - A.

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.
ippContextMatchErr	Indicates an error condition if any of the IppsGFPXQState or IppsGFPXQElement context parameters does not match the operation.
