xpmmetaget

This queries the default metadata from messages that are produced by xpmId.

xpmmetaget ?-rw | -ro | -all? xpmId ?key?

-rw and -ro restrict the list to the read-write, or modifiable, and read-only key lists.

If you do not specify a key value, then the available metadata keys are returned.

If you specify a key value, then the metadata that is associated with that key returns.

Manipulating data

You can manipulate metadata in the Translation tool, so that an xlate can configure HTTP headers/URL and modify DRIVERCTL during xlate.

This, and other metadata fields, is accessed in xlate using the xpmmetaget and xpmmetaset commands.

Example:

set udata [xpmmetaget $xlateId USERDATA]
