Call this CWI interface as follows:

L     R15,CEECAALEOV-CEECAA(,R12)     CAA address is in R12
L     R15,0328(,R15)
BALR  R14,R15

attr_object (input/output)

The initialized mutex attributes or read-write lock attributes object.

fc (output/optional)

The feedback code returned by the service. It indicates the degree of success in deleting the mutex attributes or read-write lock attributes object.

The following message identifiers and associated severities can be returned by the service in the feedback code fc.
