    64  *
    65  * This wrapper only makes it more comfortable to use async_data_write_*
    66  * functions to receive strings.
    67  *
    68  * @param str      Pointer to string pointer (which should be later disposed
    69  *                 by free()). If the operation fails, the pointer is not
    70  *                 touched.
    71  * @param max_size Maximum size (in bytes) of the string to receive. 0 means
    72  *                 no limit.
    73  * @param received If not NULL, the size of the received data is stored here.
    74  *
    75  * @return Zero on success or a value from @ref errno.h on failure.
