ECCPSetPointAtInfinity¶
Sets the point at infinity.
Syntax¶
IppStatus ippsECCPSetPointAtInfinity(IppsECCPPointState* pPoint, IppsECCPState* pECC);
Include Files¶
ippcp.h
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 is NULL. |
ippStsContextMatchErr |
Indicates an error condition if one of the contexts pointed by pPoint or pECC is not valid. |
