PAMS API of Oracle MessageQ Changed in Itanium Version (Formerly BEA MessageQ) (Doc ID 1682428.1)

Last updated on MAY 11, 2021

Applies to:

Oracle MessageQ - Version 5.0 and later
HP OpenVMS Alpha
HP OpenVMS Itanium


When MessageQ applications are ported from OpenVMS/Alpha to OpenVMS/Itanium, it appears the API call "pams_get_msga" is changed for parameter "actrtn":
  void (*func) (int32*) on Apha,
  int32 (*func) (int32*) on Itanium.

So the action routine must return an int32 status code to the caller and some compilers are detecting: C++ compiler requests new status code while Pascal seems to be working well.
1- what is the reason for changing the API in the first place?
2- which status codes should be returned by the action routine in which situations?
3- should code(s) such as Pascal be changed accordingly?
