H-Series Guardian Procedures
The H-series Guardian procedures support many of the G-series operating system
features and provide further process control functionality. For details about how to
convert applications to use the H-series Guardian procedures, refer to the H-Series
Application Migration Guide. Refer to the Guardian Programmer’s Guide for further
information about how to use the operating system features.
Superseded Guardian procedures continue to be supported for compatibility and are
still documented in this manual. They are marked as “superseded” and are listed in
Appendix G, Superseded Guardian Procedure Calls and Their Replacements.
G-Series Guardian Procedures
The G-series Guardian procedures include the features of the D-series operating
system. Some features on the G-series RVUs are not available on D-series RVUs.
For details on how to convert applications to use G-series Guardian procedures, refer
to the G-Series System Migration Planning Guide. For details on how to use the
features of the operating system, refer to the Guardian Programmer’s Guide.
Superseded Guardian procedures continue to be supported for compatibility and are
still documented in this manual. They are marked as “superseded” and are listed in
Appendix G, Superseded Guardian Procedure Calls and Their Replacements.
For G-series and later Guardian applications, the variable supplied as an output
parameter in a call to a Guardian procedure cannot be the same as, nor overlap, any
of the other reference parameters to the routine.
Interprocess communication is not supported when G-series nodes and C-series
nodes both exist in a network.
