    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    Specifies the pasteboard to be checked for the presence of a
    broadcast message. The pasteboard-id argument is the address of
    an unsigned longword that contains the pasteboard identifier.

    The pasteboard identifier is returned by SMG$CREATE_PASTEBOARD.

 message

    type:         character string
    access:       write only
    mechanism:    by descriptor

    A string that receives the broadcast message, if such a message
    is available. The message argument is the address of a descriptor
    that points to the string into which the message text is written.
    If this argument is omitted, the broadcast message is discarded.

 message-length

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       write only
    mechanism:    by reference

    Receives the actual length of the broadcast message. The message-
    length argument is the address of an unsigned word into which is
    written the length of the message.

 message-type

    OpenVMS usage:word_unsigned
    type:         word (unsigned)
    access:       write only

    Receives the type of broadcast message. The message-type argument
    is the address of an unsigned word into which is written the type
    of message. Values for message-type are defined by the $MSGDEF
    library definition. If the value for message-type is not MSG$_
    TRMBRDCST, the condition value returned is SMG$_NOBRDMSG.
