ECCPGetPoint¶
Retrieves coordinates of the point on the elliptic curve defined over GF(p).
Syntax¶
IppStatus ippsECCPGetPoint(IppsBigNumState* pX, IppsBigNumState* pY, const IppsECCPPointState* pPoint, IppsECCPState* pECC);
Include Files¶
ippcp.h
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¶
The function retrieves the coordinates of the point on the elliptic curve defined over a prime finite field GF(p) from the point context and allocates them in accordance with the set pointers pX and pY.
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. |
