New Revision: 40210
URL: http://svn.reactos.org/svn/reactos?rev=40210&view=rev
Log:
- Remove the readln function, it did more than it should and had quite a hacky interface
The same functionality is implemented inside ProcessDebugData now, with cleaner and no
duplicated code :-)
- Add more error and result messages
- Change the value for "maxcrashes" to 10 (the value used on the Buildslave)
- Add more comments
- Fix indentation a bit
