ECCPPointGetSize

Gets the size of the IppsECCPPoint context in bytes for a point on the elliptic curve point defined over GF(p).

Syntax

IppStatus ippsECCPPointGetSize(int feBitSize, int* pSize);

Parameters

feBitSize	Size (in bits) of the field element.
pSize	Pointer to the context size.

Description

This function is declared in the ippcp.h file. The function computes the context size in bytes for a point on the elliptic curve defined over a prime finite field GF(p).

Context is a structure IppsECCPPoint intended for storing the information about a point on the elliptic curve defined over GF(p).

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.
ippStsSizeErr	Indicates an error condition if the value of the parameter feBitSize is less than 2.
