GFpSetElement

Assigns a value to an element of the finite field.

Syntax

IppStatus ippsGFpSetElement(const Ipp32u*
pA
, int
lenA
, IppsGFpElement*
pR
, IppsGFpState*
pGFp
);
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 assigned.
pGFp
Pointer to the context of the finite field.
Description
This function copies (and converts if needed) the value from the user-defined
pA
 buffer to the
IppsGFpElement
 context of the finite field element. If
pR
 is
NULL
,
GFpSetElement
 assigns zero to the element.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition in the following cases:
  • Either
    pR
     or
    pGFp
     is
    NULL
    .
  • The length of the element
    lenA
     is greater than zero and the pointer
    pA
     is
    NULL
    .
ippStsContextMatchErr
Indicates an error condition if any of the
pGFp
 and
pR
 context parameters does not match the operation.
ippStsSizeErr
Indicates an error condition in the following cases:
  • lenA
     is not equal to the length of an element of the finite field.
  • The maximum length of the element stored in the context
    pR
     exceeds the maximum length of an element of the finite field specified by the context
    pGFp
    .
ippStsOutOfRangeErr
Indicates an error condition if the value contained in
pA
 exceeds the modulus
q
 of the basic prime finite field.
