:Hello,
:
:a small correction to the example code in the "userapi" chapter on your site: 
:the read() function shall not update the [per-thread] errno value if it is 
:..
:(shouldn't it be returned from the kernel just as in the case of successful 
:read?):
:
:	error = lwkt_domsg(&syscall_port, msg);
:	if (error) {
:		curthread->td_errno = error;
:		msg->result = -1;
:	}
:	return(msg->result);
