The XATMI interface is an application programming interface (API) which serves for client/server mode communication and conforms to the DTP model specified by X/Open, an open system standardization institute. OpenTP1 can use the XATMI interface for communication between UAP processes.

• Relationship between OpenTP1 UAP types and XATMI interface
  SUPs and SPPs can use the XATMI interface for communication. MHPs cannot use XATMI interface functions. To both the SUP and SPP, link stubs created from the XATMI interface definition file.
  As far as UAP process environments, methods for starting and termination, and OpenTP1 UAP operations are concerned, client/server mode communication through the XATMI interface is similar to client/server mode communication using OpenTP1 RPCs (dc_rpc_call()) unless otherwise specified.
