Initializes the IppsGFPXECPoint context of a point on the elliptic curve.
Syntax
IppStatus ippsGFPXECPointInit(IppsGFPXECPoint *pPoint, const IppsGFPXElement *pX, const IppsGFPXElement *pY, IppsGFPXECState *pEC);
Parameters
pPoint |
Pointer to the IppsGFPXECPoint context being initialized. |
pX, pY |
Pointers to the X and Y coordinates of the point on the elliptic curve. |
pEC |
Pointer to the context of the elliptic curve. |
Description
This function is declared in the ippcp.h file. The function initializes the IppsGFPXECPoint context and sets up the specific coordinates of the elliptic curve point.
Note
Setting the pX and pY pointers to NULL initializes the context for the point at infinity.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if the pEC pointer is NULL. |
ippStsContextMatchErr |
Indicates an error condition if any of the context parameters does not match the operation. |
