ECCPPointGetSize
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
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 isNULL.
- ippStsSizeErr
- Indicates an error condition if the value of the parameterfeBitSizeis less than 2.
