◆ n_http_request_parse()

n_http_req_status n_http_request_parse	(	const char *	buf,
		size_t	len,
		n_http_request *	out )

parse an HTTP/1.1 request head from [buf, buf+len)

Returns N_HTTP_REQ_OK only when a complete head (through CRLFCRLF) is present and every rule holds: the method is GET or POST; the target is origin-form ('/'-prefixed, no spaces or control bytes, no fragment, within N_HTTP_REQ_PATH_MAX); the version is HTTP/1.0 or 1.1; at most N_HTTP_REQ_HEADERS_MAX headers; no Transfer-Encoding; at most one Content-Length, a valid non-negative integer within N_HTTP_REQ_BODY_MAX. On OK, out is filled and out->head_len marks the body start.

Returns N_HTTP_REQ_INCOMPLETE when no CRLFCRLF has arrived yet and the buffered bytes are still under N_HTTP_REQ_HEAD_MAX (read more), and N_HTTP_REQ_ERROR for anything malformed, unsupported, or over the head cap. Bounded and over-read safe on every path.
