Syntax

IppStatus ippsGFpECCmpPoint(const IppsGFpECPoint*

, const IppsGFpECPoint*
pQ
, IppECResult*
pResult
, IppsGFpECState*
pEC
);
Include Files
ippcp.h
Parameters
pA
Pointer to the context of the first elliptic curve point.
pQ
Pointer to the context of the second elliptic curve point.
pResult
Pointer to the result of the comparison.
pEC
Pointer to the context of the elliptic curve.
Description
This function compares the coordinates of two points on the elliptic curve over the finite field and returns the result in 
pResult
. The result of the comparison may have the following values:
ippECPointIsEqual
The points are equal.
ippECPointIsNotEqual
The points are not equal.
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 condition if any of the points does not belong to the finite field over which the elliptic curve is initialized.
