GFpGetElement
Extracts an element of the finite field from the context.
Syntax
IppStatus ippsGFpGetElement(const IppsGFpElement* pA, Ipp32u* pDataA, int lenA, IppsGFpState* pGFp);
Include Files
ippcp.h
Parameters
pA |
Pointer to the context of the finite field element. |
pDataA |
Pointer to the data array to copy the finite field element from. |
lenA |
Length of the data array. |
pGFp |
Pointer to the context of the finite field. |
Description
This function copies the element of the finite field from the IppsGFpElement context to the user-defined pDataA buffer. 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 any of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error condition if any of IppsGFpState and IppsGFpElement context parameters does not match the operation. |
ippStsOutOfRangeErr |
The input elements do not belong to the finite field specified by the context pGFp |
ippStsSizeErr |
The length of the data array is negative or less than the finite field element length. |
