GFpECGetSize

Gets the size of an elliptic curve over the finite field.

Syntax

IppStatus ippsGFpECGetSize(const IppsGFpState*
pGF
, int*
pSize
);
Include Files
ippcp.h
Parameters
pGF
Pointer to the
IppsGFpState
context of the underlying finite field.
pSize
Buffer size in bytes needed for the
IppsGFpECState
context.
Description
This function returns the size of the buffer associated with the
IppsGFpECState
context, suitable for storing data for the elliptic curve over the finite field specified by the context
pGF
.
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 the
