* line;
* if dump_or_print is false, and *buf is not NULL, then dump content to
* the memory pointed by *buf, and adjust *buf and *len according to actual
* bytes dumped, and return the actual dumped length

* @param dump_or_print whether to print to stdout or dump to buf
* @param buf [INOUT] pointer to the buffer
* @param len [INOUT] pointer to remaining length
