Include Files
ippcp.h
Parameters
pSize
Pointer to the size (in bytes) of the
IppsECCPState
context for a standard elliptic curve.
Description
Each of these functions computes the size of the context in bytes for the elliptic curve cryptosystem based on a specific standard elliptic curve. For a list of these curves, see table Standard Elliptic Curves.
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
.
