Include Files
ippcp.h
Parameters
pX
,
pY
Pointers to the
X
 and
Y
 coordinates of the point on the elliptic curve.
pPoint
Pointer to the
IppsGFpECPoint
 context.
pEC
Pointer to the context of the elliptic curve.
Description
This function sets up the coordinates of a point on the elliptic curve over the finite field.
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 any of the specified contexts does not match the operation.
ippStsOutOfRangeErr
Indicates an error if the point coordinates (
pX
,
pY
) do not belong to the finite field over which the elliptic curve is initialized.
