Arguments

 

device-name

   OpenVMS usage:device_name
   type:         character string
   access:       read only
   mechanism:    by descriptor

   Device name that LIB$ASN_WTH_MBX passes to the $ASSIGN service.
   The device-name argument is the address of a descriptor pointing
   to the device name.
 

maximum-message-size

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       read only
   mechanism:    by reference

   Maximum message size that can be sent to the mailbox; LIB$ASN_
   WTH_MBX passes this argument to the $CREMBX service. The maximum-
   message-size argument is the address of a signed longword integer
   containing this maximum message size.
 

buffer-quota

   OpenVMS usage:longword_signed
   type:         longword integer (signed)
   access:       read only
   mechanism:    by reference

   Number of system dynamic memory bytes that can be used to buffer
   messages sent to the mailbox; LIB$ASN_WTH_MBX passes this
   argument to the $CREMBX service. The buffer-quota argument is
   the address of a signed longword integer containing this buffer
   quota.
 

device-channel

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

   Device channel that LIB$ASN_WTH_MBX receives from the $ASSIGN
   service. The device-channel argument is the address of an
   unsigned word integer into which $ASSIGN writes the device
   channel.
 

mailbox-channel

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

   Mailbox channel that LIB$ASN_WTH_MBX receives from the $CREMBX
   service. The mailbox-channel argument is the address of an
   unsigned word integer into which $CREMBX writes the mailbox
   channel.
