.. _eccppointgetsize:



ECCPPointGetSize
================


Gets the size of the IppsECCPPoint context in bytes for a point on the
elliptic curve point defined over GF(*p*).


Syntax
------


IppStatus ippsECCPPointGetSize(int feBitSize, int\* pSize);


Include Files
-------------


``ippcp.h``


Parameters
----------


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

   * - feBitSize   
     - Size (in bits) of the field element.
   * - pSize   
     - Pointer to the context size.




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


The function computes the context size in bytes for a point on the
elliptic curve defined over a prime finite field GF(*p*).


*Context* is a structure IppsECCPPoint intended for storing the
information about a point on the elliptic curve defined over GF(*p*).


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.
   * - ippStsSizeErr   
     - Indicates an error condition if the value of the parameter feBitSize is less than 2.
