Subject: [9front] question about httpd
Date: Tue, 2 Aug 2022 18:51:05 +0200 (CEST)	[thread overview]
Message-ID: <1363970938.169268.1659459065934@office.mailbox.org> (raw)

Hello, 

I have looked at the code, and have a question about the redirectinit() function in /sys/src/cmd/ip/httpd/redirect.c:

void
redirectinit(void)
{
	static Biobuf *b = nil;
	static Qid qid;
	char *file, *line, *s, *host, *field[3];
	static char pfx[] = "http://";

	file = "/sys/lib/httpd.rewrite";
	if(b != nil){
		if(	(Bfildes(b), &qid) == 0)
			return;
		Bterm(b);
	}
...
}

In which cases could b be nil? And since it appears more often in the function, what do "B" (Biobuf, Bfildes, Bterm, ...) and "Q" (Qid) stand for?

Many thanks in advance and best regards, 
sahu
