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 isNULL.
- ippStsContextMatchErr
- Indicates an error condition if any ofIppsGFpStateorIppsGFpElementcontext parameter does not match the operation.
- ippStsOutOfRangeErr
- Indicates an error condition in the following cases:
- the elementpAdoes not belong to the finite field specified by the contextpGFp.
- the elementpParentBdoes not belong to the ground field of the finite field specified by the contextpGFp.
- ippStsBadArgErr
- Indicates an error condition if the contextpGFpdoes not specify a prime field.
