Portable API Presentation Procedures
This chapter describes the interface between the TP Desktop Connector
gateway and customer-written presentation procedures. It also describes the
interfaces on portable clients for customer-written action routines to perform
version checking.
3.1 Summary of Portable API Presentation Procedures
Presentation procedures are customer-written routines that the TP Desktop
Connector gateway calls when an exchange step occurs in a ACMS task with
either the FORM I/O or REQUEST I/O attribute. Table 3–1 summarizes
the presentation procedures available in a nonblocking session. These are
not applicable to a forced nonblocking session. For more information on
presentation procedures, refer to Compaq TP Desktop Connector for ACMS
Client Application Programming Guide.
