APSURLST parameter area (resource list)
APSURLST is a control block that PSF builds when it needs to provide
information to the exit about a specific resource. Typically, PSF
builds one RLST entry for each resource associated with the current
call to the exit. If multiple RLST entries are required to describe
all the resources to the exit, the RLST entries are linked to form
a single-headed, double-threaded chain. The first, or only, RLST entry
is pointed to by XTP7LSTP in the XTP7 control block area.
Note:
Exit 7 must never modify the pointers RLSTPRVS, RLSTNEXT,
and RLSTEXTP as defined in APSURLST.
All the fields in APSURLST are read by the exit; however, some
fields contain information that is valid only for certain exit calls
and certain resource types. Also, most fields in APSURLST are not
intended to be written to by the exit. PSF looks for changes to specific
fields after certain calls to the exit. For more details, see APSURLST fields.
Figure 98 shows the format of APSURLST.
