IWMQCXIT macro — Queue Manager Connect Exit

IWMQCXIT will invoke the Queue Manager Connect exit specified. This exit is responsible for taking the action indicated for the associated Queue Manager. The return/reason codes for IWMQCXIT are those set by the exit invoked.

The list form of IWMQCXIT is intended for use by the exit routine to map the input parameters. The execute and standard form of IWMQCXIT are intended for use only by the operating system.

The exit environment is described in the environment description below. The parameter list is in pageable storage addressable in the current address space, but is not guaranteed to be in the key of the exit as it is not expected to be changed by the exit. Upon entry to the exit, the register contents are as follows:

• Register 0 = not defined
• Register 1 contains the address of a parameter list as formatted by the list form of this macro, IWMQCXIT MF=(L).
• Registers 2-13 = not defined
• Register 14 = return address
• Register 15 = entry point address

Upon entry to the exit, the access register contents are undefined.

Upon return from the exit, the register contents are as follows:

• Register 0 = Reason code if GR15 return code is non-zero
• Registers 1-14 = not defined (need not be restored to value on entry)
• Register 15 = Return code

Upon return from the exit, the access register contents are unchanged.
