ECCPSetPointAtInfinity

Sets the point at infinity.

Syntax

IppStatus ippsECCPSetPointAtInfinity(IppsECCPPointState*
pPoint
, IppsECCPState*
pECC
);
Include Files
ippcp.h
Parameters
pPoint
Pointer to the context of the elliptic curve point.
pECC
Pointer to the context of the elliptic cryptosystem.
Description
The function sets the point at infinity. The context of the elliptic curve point must be already created by functions:
ECCPPointGetSize
and
ECCPPointInit
. 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
pPoint
or
pECC
is not valid.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors.
