Listing DLLs

Native Inspect maintains a list of the loadfiles that compose the current program. You

can display the list of loadfiles by entering the info command with the dll option.

Loading Symbols for DLLs

Native Inspect automatically loads symbols for the program file and for explicitly loaded

DLLs. You must explicitly load symbols for other DLLs using the symbol command or

symbol-file command. To explicitly add additional symbol files at a specific address,

use the add-symbol-file command.

Addressing Symbols for DLLs Loaded at Another Address

If a user loads a symbol file for a DLL before a program call to dlopen() to load the

DLL, Native Inspect uses the preferred address of the DLL as the basis for symbol

address calculations. Then, when the DLL is loaded, Native Inspect again attempts to

load the symbols using the actual load address for the DLL.

Setting Breakpoints

Native Inspect does not support the ability to set breakpoints on DLL functions before

the DLL is loaded; you must wait until the DLL is loaded. Use the add-symbol-file

command if you want to specify the base address relative to which symbolic addresses

are calculated.

Handling Events

When Native Inspect receives an event, it informs you what event has occurred and

then updates the debugging context (that is, information specific to the current process,

such as breakpoints, loaded DLLs, and the current register values).

The type of events that have the most impact on debugging with Native Inspect are

debugging events, which typically suspend a program under debugger control. For

example, a breakpoint is a debugger-induced debugging event.

Specific responses to significant events are listed in Table 1-2.

Assessing Your Location After an Event

If you are uncertain about your current program location after an event occurs, you can

list the current frame by using the frame command, select-frame command:

(eInspect 6,679): frame

#0 test_complexTypes() () at \SYS03.$D007.SYMBAT1.SCXXTST:424

424 printf( "%s test_complexTypes\n", getStepPrefix( 1 ) );
