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.
If the
lenA
parameter value equals zero, the function initializes a zero element. If the value is less than zero, the function fails.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition in the following cases:
  • lenA
    is not zero and any of the specified pointers is
    NULL
    .
  • lenA
    is zero and
    pR
    or
    pGFp
    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.
