ECCPSetPointAtInfinity
ECCPSetPointAtInfinity
Sets the point at infinity.
Syntax
IppStatus ippsECCPSetPointAtInfinity(IppsECCPPointState*
pPoint
, IppsECCPState*
pECC
);

Parameters
- pPoint
- Pointer to the context of the elliptic curve point.
- pECC
- Pointer to the context of the elliptic cryptosystem.
Description
The function sets the point at infinity. The context of the elliptic curve point must be already created by functions:
ECCPPointGetSize
and ECCPPointInit
. The elliptic curve domain parameters must be hitherto defined by one of the functions: ECCPSet
or ECCPSetStd
.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 isNULL.
- ippStsContextMatchErr
- Indicates an error condition if one of the contexts pointed bypPointorpECCis not valid.
