GFPXECPointGetSize

Gets the size of the IppsGFPXECPoint context of a point on the elliptic curve.

Syntax

IppStatus ippsGFPXECPointGetSize(const IppsGFPXECState *pEC, Ipp32u *stateSizeInBytes);

Parameters

pEC	Pointer to the context of the elliptic curve.
stateSizeInBytes	Buffer size in bytes needed for the IppsGFPXECPoint context.

Description

This function is declared in the ippcp.h file. The function returns the size of the buffer associated with the IppsGFPXECPoint context, suitable for storing data for a point on the elliptic curve over the GF(p^d) field.

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 any of the context parameters does not match the operation.
