// Name: ippsGFpElementGetSize
//
// Purpose: Gets the size of the context for an element of the finite field.
//
// Returns:                   Reason:

//    ippStsContextMatchErr     incorrect pGFp's context id
//    ippStsNoErr              no error
//
// Parameters:
//    nExponents      Number of exponents.
//    ExpBitSize      Maximum bit size of the exponents.
//    pGFp            Pointer to the context of the finite field.
//    pBufferSize     Pointer to the calculated buffer size in bytes.
