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.
