Debug Identification Area
9
This area shows the name of the executable program that the currently displayed process
is running.
There is also a label showing the qualifier specifier for this process. See “Qualifier
Specifiers” on page 7-13. For threaded programs on Linux, the process ID in the
qualifier indicates which of the thread processes last stopped. See “Multithreaded
Programs” on page 3-35.
Debug Source Lock Button
9
The Debug Window contains a source lock button. The source lock button looks like a
little padlock.
You can lock the source display by clicking on the source lock button. The padlock
changes from being unlocked to locked, and the button is highlighted with the selection
color. This indicates that the source display is locked. Click on the button again to
unlock.
A locked source display does not change which file is displayed unless you explicitly
change it. These actions explicitly change the source display:
• Issuing a list command in the command area of the window.
• Using the Source menu.
• Issuing an up, down or frame command in the command area of the window.
These events can cause an unlocked source display to change:
• The currently displayed process stops.
• The source file for the currently displayed process changes because of an
action in another window.
Debug Source File Name
9
This area shows the name of the source file displayed in the debug source display. See
“Debug Source Display” on page 9-37. If there is no source file displayed, then this field
shows No Source File. If NightView cannot find the source file, this field shows
Cannot find: filename.
If the source display area is in disassembly display mode, this field shows information
about the region displayed, such as Function main.
