Description
This function computes the conjugate of an element of the finite field GF(). If the element of the GF() field is the polynomial
p
2
p
2
x + a
, the conjugate element is equal to x – a
, where a
is an element of the ground field GF(p
).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 ofIppsGFpStateandIppsGFpElementcontext parameters does not match the operation.
- ippStsOutOfRangeErr
- Indicates an error condition if the elementpAdoes not belong to the finite field specified by the contextpGFp.
- ippStsBadArgErr
- Indicates an error condition if the elementpAdoes not belong to the GF(p) field.2
