ECCPSetPointAtInfinity

Sets the point at infinity.

Syntax

IppStatus ippsECCPSetPointAtInfinity(IppsECCPPoint* pPoint, IppsECCPState* pECC);

Parameters

pPoint	Pointer to the context of the elliptic curve point.
pECC	Pointer to the context of the elliptic cryptosystem.

Description

This function is declared in the ippcp.h file.

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.
