ECCPSetPoint

Sets coordinates of a point on the elliptic curve defined over GF(p).

Syntax

IppStatus ippsECCPSetPoint(const IppsBigNumState* pX, const IppsBigNumState* pY, IppsECCPPoint* pPoint, IppsECCPState* pECC);

Parameters

pX	Pointer to the x-coordinate of the point on the elliptic curve.
pY	Pointer to the y-coordinate of the point on the elliptic curve.
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 coordinates of a point on the elliptic curve defined over a prime finite field GF(p).

The context of the point on the elliptic curve 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 pX, pY, pPoint, or pECC is not valid.
