GFPECCmpPoint

Compares two points on the elliptic curve over the GF(p) field.

Syntax

IppStatus ippsGFPECCmpPoint(const IppsGFPECPoint *pA, const IppsGFPECPoint *pB, IppsElementCmpResult *result, IppsGFPECState *pEC);

Parameters

pA	Pointer to the context of the first point on the elliptic curve.
pB	Pointer to the context of the second point on the elliptic curve.
result	The result of the parameter verification.
pEC	Pointer to the context of the elliptic curve.

Description

This function is declared in the ippcp.h file. The function compares coordinates of two points on the elliptic curve over the GF(p) field and returns the result in *result. The result of the comparison may have the following values:

ippElementEQ	The points are equal.
ippElementNE	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 context parameters does not match the operation.
