    </P
><P
>&#13;     If the message is too large to fit in the queue, your script will wait
     until another process reads messages from the queue and frees enough
     space for your message to be sent.
     This is called blocking; you can prevent blocking by setting the
     optional <TT
CLASS="parameter"
><I
>blocking</I
></TT
> parameter to <TT
CLASS="constant"
><B
>FALSE</B
></TT
>, in which
     case <B
CLASS="function"
>msg_send()</B
> will immediately return <TT
CLASS="constant"
><B
>FALSE</B
></TT
> if the
     message is too big for the queue, and set the optional
     <TT
CLASS="parameter"
><I
>errorcode</I
></TT
> to EAGAIN, indicating that you should
     try to send your message again a little later on.
    </P
><P
>&#13;     The optional <TT
CLASS="parameter"
><I
>serialize</I
></TT
> controls how the
     <TT
CLASS="parameter"
><I
>message</I
></TT
> is sent.  <TT
CLASS="parameter"
><I
>serialize</I
></TT
>
     defaults to <TT
CLASS="constant"
><B
>TRUE</B
></TT
> which means that the <TT
CLASS="parameter"
><I
>message</I
></TT
> is
     serialized using the same mechanism as the session module before being
     sent to the queue.  This allows complex arrays and objects to be sent to
     other PHP scripts, or if you are using the WDDX serializer, to any WDDX
     compatible client.

>&#13;     Upon successful completion the message queue data structure is updated as
     follows: <TT
CLASS="parameter"
><I
>msg_lspid</I
></TT
> is set to the process-ID of the
     calling process, <TT
CLASS="parameter"
><I
>msg_qnum</I
></TT
> is incremented by 1 and
     <TT
CLASS="parameter"
><I
>msg_stime</I
></TT
> is set to the current time.
