This utility is intended to be used in startup scripts to ensure an object is cataloged.

Lookup objectname in the process indicated by the -proc parameter, or in the root process by default. The utility waits until the handle has been cataloged with the given name unless the -wait or -nowait parameter has been specified in which case the utility will exit after the specified timeout.

When the handle is cataloged the utility returns with exit code 0. If a specified timeout elapses before the handle is cataloged then the utility returns with a status code of 1.

If multiple names a specified then the utility returns after all have been cataloged. If a timeout is specified then it applies to each name in turn. if any name is not cataloged before the timeout, the utility will return a value indicating how many names were not cataloged.
