+ * A test for nonblocking connect. Functions tested include PR_Connect,
+ * PR_Poll, and PR_GetConnectStatus.
+ *
+ * The test should be invoked with a host name, for example:
+ * nbconn www.netscape.com
+ * It will do a nonblocking connect to port 80 (HTTP) on that host,
+ * and when connected, issue the "GET /" HTTP command.
+ *
+ * You should run this test in three ways:
+ * 1. To a known web site, such as www.netscape.com. The HTML of the
+ * top-level page at the web site should be printed.
+ * 2. To a machine not running a web server at port 80. This test should
+ * fail. Ideally the error code should be PR_CONNECT_REFUSED_ERROR.
+ * But it is possible to return PR_UNKNOWN_ERROR on certain platforms.
+ * 3. To an unreachable machine, for example, a machine that is off line.
+ * The test should fail after the connect times out. Ideally the
+ * error code should be PR_IO_TIMEOUT_ERROR, but it is possible to
+ * return PR_UNKNOWN_ERROR on certain platforms.
