Listing information about the use of virtual storage above the bar

Authorized programs can use the IARV64 LIST request to obtain information about memory objects in the caller's address space. The system returns the information in a work area you provide. The V64LISTPTR parameter defines the first address of this work area; the V64LISTLENGTH identifies the length of the area. The parameter list macro is mapped by IARV64WA.

The system returns the following information about usable areas (not guard areas) of memory objects:

Beginning address
Ending address
Storage key
Shared or private indicator
Multiple guard areas indicator

To request a list of shared memory objects defined for the system via GETSHARED specify V64SHARED=YES.
