Extracting a Service Definition

The IWMDEXTR macro allows a program to extract a service definition from the WLM couple data set. Once the service definition is extracted, then a service administrator can make changes.

A caller should issue IWMDEXTR specifying QUERYLEN to determined the storage required for the service definition The service definition returned by IWMDEXTR is not serialized against future installs, so the length returned could change before a caller can issue IWMDEXTR again. The caller should issue IWMDEXTR in a loop, checking return and reason codes, and obtaining a larger storage area if necessary.
