Summary
NOTE: This procedure cannot be called by native processes. Although this procedure is supported
for TNS processes, it should not be used for new development.
The XSTACKTEST procedure, used with LASTADDRX and XBNDSTEST procedures, checks stack
limits. XSTACKTEST ensures that adequate stack space is available and returns a set of constants
to be used with the XBNDSTEST procedure.
