Expand description

\brief Perform a modular reduction. R = A mod B

\param R The destination MPI for the residue value. This must point to an initialized MPI. \param A The MPI to compute the residue of. This must point to an initialized MPI. \param B The base of the modular reduction. This must point to an initialized MPI.

\return \c 0 if successful. \return #MBEDTLS_ERR_MPI_ALLOC_FAILED if a memory allocation failed. \return #MBEDTLS_ERR_MPI_DIVISION_BY_ZERO if \p B equals zero. \return #MBEDTLS_ERR_MPI_NEGATIVE_VALUE if \p B is negative. \return Another negative error code on different kinds of failure.
