Parameters
----------


.. list-table:: 
   :header-rows: 0

   * - pECC   
     - Pointer to the cryptosystem context based on a standard elliptic curve.




Description
-----------


Each of these functions initializes the context of the elliptic curve
cryptosystem based on a specific standard elliptic curve. For a list of
these curves, see table `Standard Elliptic
Curves <functions-based-on-gf-p.html>`__.


Return Values
-------------


.. list-table:: 
   :header-rows: 0

   * - 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.
