- * If Socket Tracing is active, messages sent and received will be
- * timestamped and dumped (to stdout) in standard hex-dump format. E.g.,
- *
- * 1116612359156140:
- * 28F0: 48 65 6C 6C 6F 2C 20 77   6F 72 6C 64 21 00    Hello, world!.
- *
- * The timestamp is not formatted to be meaningful except as an increasing
- * value of seconds.microseconds, which is good enough to correlate two
- * sides of a message exchange and to figure durations.
- *
- * Code to perform Socket tracing will be compiled in if PKIX_SOCKETTRACE
- * is defined, but that doesn't mean socket tracing is active. Tracing also
- * requires that the Boolean socketTraceFlag is set to PKIX_TRUE. That is
- * the default value, but it can be overridden by using the debugger to
- * change its value -- allowing tracing to be turned on and off at various
- * breakpoints -- or by setting the environment variable SOCKETTRACE. A
- * value of 1 sets socketTraceFlag to PKIX_TRUE (tracing on), and any other
- * value sets socketTraceFlag to PKIX_FALSE (tracing off). The environment
- * value is checked during system initialization.

- * FUNCTION: pkix_pl_Socket_CreateByHostAndPort
- * DESCRIPTION:
- *
- *  This function creates a new Socket, setting it to be a server or a client
- *  according to the value of "isServer", setting its timeout value from
- *  "timeout", host from "hostname", and port number from "portNum", and stores
- *  the status at "pStatus" and the created Socket at "pSocket".
- *
- *  If isServer is PKIX_TRUE, it is attempted to create the socket with an ip
- *  address of PR_INADDR_ANY.
- *
- * PARAMETERS:
- *  "isServer"
- *      The Boolean value indicating if PKIX_TRUE, that a server socket (using
- *      Bind, Listen, and Accept) is to be created, or if PKIX_FALSE, that a
- *      client socket (using Connect) is to be created.
- *  "timeout"
- *      A PRTimeInterval value to be used for I/O waits for this socket. If
- *      zero, non-blocking I/O is to be used.
- *  "hostname"
- *      Address of a character string consisting of the server's domain name.
- *  "portNum"
- *      UInt16 value of the port number for the desired socket.
- *  "pStatus"
- *      Address at which the PRErrorCode resulting from the create is
- *      stored. Must be non-NULL.
- *  "pSocket"
- *      The address at which the Socket is to be stored. Must be non-NULL.
- *  "plContext"
- *      Platform-specific context pointer.
- * THREAD SAFETY:
- *  Thread Safe (see Thread Safety Definitions in Programmer's Guide)
- * RETURNS:
- *  Returns NULL if the function succeeds.
- *  Returns a Socket Error if the function fails in
- *      a non-fatal way.
- *  Returns a Fatal Error if the function fails in an unrecoverable way.
