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. |
