Syntax

IppStatus ippsGFpAdd_PE(const IppsGFpElement*

, IppsGFpElement*
pR
, IppsGFpState*
pGFp
);
Include Files
ippcp.h
Parameters
pA
Pointer to the context of the first element of the finite field to be added.
pParentB
Pointer to the context of the second element to be added, which is an element of the parent finite field.
pR
Pointer to the context of the resulting element of the finite field.
pGFp
Pointer to the context of the finite field.
Description
The function computes the sum of the elements of the finite field specified by the context
pGFp
and its ground finite field. The following pseudocode represents this operation:
R = A + B
.
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
IppsGFpState
or
IppsGFpElement
context parameter does not match the operation.
ippStsOutOfRangeErr
Indicates an error condition in the following cases:
  • the element
    pA
    does not belong to the finite field specified by the context
    pGFp
    .
  • the element
    pParentB
    does not belong to the ground field of the finite field specified by the context
    pGFp
    .
ippStsBadArgErr
Indicates an error condition if the context
pGFp
does not specify a prime field.
