It returns negative value on error. dstr_get_data copies data from internal buffers into given character array allocated by caller. The data size can be determined by dstr_get_data_length call. dstr_get_data_str copies data from internal buffers into internally allocated string. This string is returned in the dst parameter. Functions dstr_get_data and dstr_get_data_str return 0 if successful, nonzero otherwise. Function dstr_get_data_length returns negative value on error, zero if there is no data in dynamic string and positive if there was no error and data present.
