GFpElementInit

Initializes the context of an element of the finite field.

Syntax

IppStatus ippsGFpElementInit(const Ipp32u* pA, int nsA, IppsGFpElement* pR, IppsGFpState* pGF);

Include Files

ippcp.h

Parameters

pA

Pointer to the data array storing the finite field element.

lenA

Length of the element.

pR

Pointer to the context of the finite field element being initialized.

pGFp

Pointer to the context of the finite field.

Description

This function initializes the memory buffer pR associated with the IppsGFpElement context and sets up the specific element of the finite field specified by the pGFp context. The initialized IppsGFpElement context is used in all the operations with this element of the finite field.

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 the pGFp context parameter does not match the operation.

ippStsSizeErr

Indicates an error condition if lenA ≤ 0.
