NAME
     mbx - Mailbox Manager (ipc) support information

DESCRIPTION
     The mbx (mailbox) manager calls implement a user-callable interprocess
     communication (IPC) facility. This facility is based on a server/client
     model of interprocess communication.

     The server creates a named mbx file and in so doing declares his
     intention to handle incoming service requests.  Through this file, the
     server may control up to 255 full-duplex conversations concurrently.
     Prospective clients of a particular service supply the mbx package with
     the name of the mbx file that the target server has created.  If the
     server agrees to provide service, it accepts the conversation and a
     full-duplex communications channel is opened between them.

     Before inter-node interprocess communication may be used, each
     participating node must initiate the mbx_helper program, either in a
     normal process running the shell or via the Display Manager command cpo
     (create_process_only).  The mbx program is found in:

          /sys/mbx/mbx_helper
