GFpInv
Computes the multiplicative inverse of an element of the finite field.
Syntax
IppStatus ippsGFpInv(const IppsGFpElement* pA, IppsGFpElement* pR, IppsGFpState* pGFp);
Include Files
ippcp.h
Parameters
pA |
Pointer to the context of the finite field element. |
pR |
Pointer to the context of the resulting element of the finite field. |
pGFp |
Pointer to the context of the finite field. |
Description
This function computes the multiplicative inverse of an element of the finite field. The following pseudocode represents this operation: R ⋅ A = 1. The finite field is specified by the context pGFp.
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 IppsGFpState and IppsGFpElement context parameters does not match the operation. |
ippStsOutOfRangeErr |
Indicates an error condition if the element pA does not belong to the finite field specified by the context pGFp. |
ippStsDivByZeroErr |
Indicates an error condition if pA is the zero element. |
ippStsBadArgErr |
Indicates an error condition if a computational error occurs. |
