- * 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.
