Summary
LOCKINFO provides information about locks (held or pending) on a local DP2 disk
volume. Each call returns information about one lock, plus as many holders/waiters as
the size of the caller’s buffer permits; successive calls can obtain information about all
the locks for a volume, file, process, or transaction.
Syntax for C Programmers
This procedure does not have a C syntax, because it is superseded and should not be
used for new development. This procedure is supported only for compatibility with
previous software.

Parameters

INT
is a file-system error code indicating the outcome of the call. See “Considerations”
for values that may be returned.

used for new development.
