GFpECSet

Sets up the parameters of an elliptic curve over a finite field.

Syntax

IppStatus ippsGFpECSet(const IppsGFpElement*
pA
, const IppsGFpElement*
pB
, IppsGFpECState*
pEC
);
Include Files
ippcp.h
Parameters
pA
Pointer to the coefficient
A
 of the equation defining the elliptic curve.
pB
Pointer to the coefficient
B
 of the equation defining the elliptic curve.
pEC
Pointer to the context of the elliptic curve.
Description
This function assigns input values to the parameters of the elliptic curve in the
IppsGFpECState
 context, if they are supplied.
Only the 
pEC
 parameter is required. You can omit the other parameters by setting their values to 
NULL
 or zero.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if
pEC
 is
NULL
.
ippStsContextMatchErr
Indicates an error condition in the following cases:
  • IppsGFpECState
     context parameter does not match the operation.
  • pA
     or
    pB
     is not zero, and the corresponding context parameter does not match the operation.
ippStsOutOfRangeErr
Indicates an error condition if
pA
 or
pB
 does not belong to the finite field specified by the
pGFp
 context.
