Arguments

 

pasteboard-id

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

   Specifies the pasteboard for which broadcast messages are to be
   trapped. 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.
 

AST-routine

   OpenVMS usage:ast_procedure
   type:         procedure value
   access:       read only
   mechanism:    by value

   The address of an AST routine to be called when a message is
   received at the pasteboard. The AST-routine argument is the
   address of the routine's procedure value.

   When the AST-routine argument is either omitted or is given a
   value of 0, the BROADCAST mode is set to synchronize. In this
   mode, you must periodically call SMG$GET_BROADCAST_MESSAGE to see
   if any broadcast messages have arrived.

   The AST routine is called with five parameters: AST-argument, R0,
   R1, PC, and PSL (on VAX systems) or PS (on Alpha systems).
 

AST-argument

   OpenVMS usage:user_arg
   type:         longword (unsigned)
   access:       read only
   mechanism:    by value

   A value to be passed to the AST routine. The AST-argument is an
   unsigned longword that contains the value to be passed to the AST
   routine.
