-/** Wrapper for receiving strings
- *
- * This wrapper only makes it more comfortable to use async_data_write_*
- * functions to receive strings.
- *
- * @param str      Pointer to string pointer (which should be later disposed
- *                 by free()). If the operation fails, the pointer is not
- *                 touched.
- * @param max_size Maximum size (in bytes) of the string to receive. 0 means
- *                 no limit.
- * @param received If not NULL, the size of the received data is stored here.
- *
- * @return Zero on success or a value from @ref errno.h on failure.
- *
