GFpSub¶
Subtracts two elements of the finite field.
Syntax¶
IppStatus ippsGFpSub(const IppsGFpElement* pA, const IppsGFpElement* pB, IppsGFpElement* pR, IppsGFpState* pGFp);
Include Files¶
ippcp.h
Parameters¶
pA |
Pointer to the context of the minuend element of the finite field. |
pB |
Pointer to the context of the subtrahend element of the 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¶
This function computes the difference of the elements of the finite
field. The following pseudocode represents this operation:
R = A - B. 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 pA or pB does not belong to the finite field specified by the context pGFp. |
