Function esp_idf_svc::sys::mbedtls_ecp_gen_keypair

pub unsafe extern "C" fn mbedtls_ecp_gen_keypair(
    grp: *mut mbedtls_ecp_group,
    d: *mut mbedtls_mpi,
    Q: *mut mbedtls_ecp_point,

\brief This function generates an ECP keypair.

\note This function uses bare components rather than an ::mbedtls_ecp_keypair structure to ease use with other structures, such as ::mbedtls_ecdh_context or ::mbedtls_ecdsa_context.

\param grp The ECP group to generate a key pair for. This must be initialized and have group parameters set, for example through mbedtls_ecp_group_load(). \param d The destination MPI (secret part). This must be initialized. \param Q The destination point (public part). This must be initialized. \param f_rng The RNG function. This must not be \c NULL. \param p_rng The RNG context to be passed to \p f_rng. This may be \c NULL if \p f_rng doesn’t need a context argument.

\return \c 0 on success. \return An \c MBEDTLS_ERR_ECP_XXX or \c MBEDTLS_MPI_XXX error code on failure.
