HP gnu source-level debugger 5992-4701 HP-UX Terminal User Interface, Starting the TUI, Main

15 The HP-UX Terminal User Interface

By default, GDB runs in line mode. For users who prefer an interface similar (though not identical) to that of the XDB debugger, HP provides a terminal user interface (TUI), which appears when you invoke the gdb command with the -tuioption.

Use the -xdboption to enable the use of a number of XDB commands. See the “XDB to WDB Transition Guide” (page 253).

15.1 Starting the TUI

Invoke the debugger using a command like the following:

gdb -xdb -tui a.out

These examples use the default terminal screen size of 24 by 80 characters. Following is a sample terminal screen window:

----------------------------------------------------------------------
30	{
31	/* Try two test cases. */
32	print_average (my_list, first, last);
33	print_average (my_list, first, last - 3);
34	}

(gdb)

The terminal window is divided into two panes: a Source pane at the top and a Command pane at the bottom. In the middle is a locator bar that shows the current file, procedure, line, and program counter (PC) address, when they are known to the debugger.

When you set a breakpoint on the main program by issuing the command

b main

an asterisk (*) appears opposite the first executable line of the program.
