Subtracts an element of the GF(p) field from an element of the GF(p^d) field.
IppStatus ippsGFPXSub_GFP(const IppsGFPXElement *pGFpxElementA, const IppsGFPElement *pGFpElementB, IppsGFPXElement *pGFpxElementR, IppsGFPXState *pGFpx);
pGFpxElementA |
Pointer to the context of the minuend element of the GF(p^d) field. |
pGFpElementB |
Pointer to the context of the subtrahend element of the GF(p) field. |
pGFpxElementR |
Pointer to the context of the resulting element of the GF(p^d) field. |
pGFpx |
Pointer to the context of the GF(p^d) field. |
This function is declared in the ippcp.h file. The function computes the difference of the elements of the GF(p^d) and GF(p) fields. The following pseudocode represents this operation: R = A - B.
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. |
ippContextMatchErr |
Indicates an error condition if any of the IppsGFPXState, IppsGFPXElement, or IppsGFPElement context parameters does not match the operation. |
