/*
 * 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.
