Function esp_idf_hal::sys::mbedtls_md_init

pub unsafe extern "C" fn mbedtls_md_init(
    ctx: *mut mbedtls_md_context_t,
)

\brief This function initializes a message-digest context without binding it to a particular message-digest algorithm.

             This function should always be called first. It prepares the
             context for mbedtls_md_setup() for binding it to a
             message-digest algorithm.
