xorriso is basically a dialog software which reacts on commands by

side effects and by messages. The side effects manipulate the state of

the ISO image model and of drives. This state can be inquired by commands

which emit messages.

All interpretation of the messages has to be done by the user of the
|
|
|
|

xorriso API. Function Xorriso_parse_line() is intended to help with
|
|
|
|
|
splitting up messages into words.

The outlist stack is handy for catching the result channel of information

The outlist stack is handy for catching the results of information

commands with large uniform output or no well recognizable message
|
|
|
|
|
prefix. Like -lsl, -getfacl, -status, -find ... -exec get_md5.
|
|
|
|
|
One should push the stack before the command, pull it afterwards, examine
|
|
|
|
|
the text list by Xorriso_lst_get_*(), and finally dispose the list.

- The message watcher is a separate program thread which uses the outlist
|
|
|
|
|
stack to catch the messages and to call user provided handler functions.
|
|
|

These functions can use Xorriso_parse_line() too, if they submit the

xorriso parameter as NULL.

xorriso parameter as NULL. They may not use the struct XorrisO object

in any way.

Synchronization between watcher and emitters of commands can be achived
|
|
|
|
|
by Xorriso_peek_outlists().
|
|
|
|
|
The main motivation for the message watcher is to inspect and display

messages of long lasting xorriso commands like -commit, -blank, -format.

|
messages of long lasting xorriso commands while they are still executing.

|
|
E.g. of -commit, -blank, -format.
|
|
|
|
|
One would normally start it before such a command and stop it afterwards.
|
|
|
|
|
But of course, the watcher can stay activated all the time and process
|
|
|
|
|
all message output via its handler calls.i
