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
);
Include Files
ippcp.h
Parameters
feBitSize
Size (in bits) of the field element.
pSize
Pointer to the context size.
Description
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.
