Expand description

\brief Perform a signed addition of MPIs: X = A + B

\param X The destination MPI. This must point to an initialized MPI. \param A The first summand. This must point to an initialized MPI. \param B The second summand. This must point to an initialized MPI.

\return \c 0 if successful. \return #MBEDTLS_ERR_MPI_ALLOC_FAILED if a memory allocation failed. \return Another negative error code on different kinds of failure.
