Summary
XBNDSTEST aids user programs in checking stack limits and/or parameter addresses.
(LASTADDRX provides a similar function.) XBNDSTEST uses constants obtained
from another procedure, XSTACKTEST, to check a specified address and its length for
potential bounds violations.
Syntax for C Programmers
Syntax for TAL Programmers
Parameters
status returned value
INT
returns one of the following values:
1 In bounds, but in a read-only segment or (on native systems only) in the
system library
0 In bounds and writable
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.
