GFpMul
======


Multiplies two elements of the finite field.


Syntax
------


IppStatus ippsGFpMul(const IppsGFpElement\* pA, const IppsGFpElement\*
pB, IppsGFpElement\* pR, IppsGFpState\* pGFp);


Include Files

Parameters
----------


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

   * -     pA   
     -  Pointer to the context of the first multiplicand element of the finite field.
   * -     pB   
     -  Pointer to the context of the second multiplicand element of the finite field.
   * -     pR   
     -  Pointer to the context of the resulting element of the finite field.
   * -     pGFp   
     -  Pointer to the context of the finite field.




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


This function computes the product of two elements of the finite field.
The following pseudocode represents this operation: ``R = A ⋅ B``. The
finite field is specified by the context pGFp.


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.
   * -     ippStsContextMatchErr   
     -  Indicates an error condition if either IppsGFpState or IppsGFpElement context parameters do not match the operation.
   * -     ippStsOutOfRangeErr   
     -  Indicates an error condition if pA or pB does not belong to the finite field specified by the context pGFp.
