/**
|
|
* A completer callback is a function that accepts three arguments:
|
|
*
|
|
* @ctl: virsh control structure
|
|
* @cmd: parsed input
|
|
* @flags: optional flags to alter completer's behaviour
|
|
*
|
|
* The @ctl contains connection to the daemon (should the
|
|
* completer need it). Any completer that requires a connection
|
|
* must check whether connection is still alive.
|
|
*
|
|
* The @cmd contains parsed user input which might be missing
|
|
* some arguments (if user is still typing the command), but may
|
|
* already contain important data. For instance if the completer
|
|
* needs domain XML it may inspect @cmd to find --domain. Using
|
|
* existing wrappers is advised. If @cmd does not contain all
|
|
* necessary bits, completer might return sensible defaults (i.e.
|
|
* generic values not tailored to specific use case) or return
|
|
* NULL (i.e. no strings are offered to the user for completion).
|
|
*
|
|
* The @flags contains a .completer_flags value defined for each
|
|
* use or 0 if no .completer_flags were specified. If a completer
|
|
* is generic enough @flags can be used to alter its behaviour.
|
|
* For instance, a completer to fetch names of domains can use
|
|
* @flags to return names of only domains in a particular state
|
|
* that the command accepts.
|
|
*
|
|
* Under no circumstances should a completer output anything.
|
|
* Neither to stdout nor to stderr. This would harm the user
|
|
* experience.
