49 "Run gdb on program FILE in buffer *gdb-FILE*.
50 The directory containing FILE becomes the initial working directory
51 and source-file directory for your debugger.
53 If `gdb-many-windows' is set to t this works best in X (depending on the size
54 of your monitor) using most of the screen. After a short delay the following
55 layout will appear (keybindings given in relevant buffer) :
57 ---------------------------------------------------------------------
59 ---------------------------------------------------------------------
60 GUD buffer (I/O of gdb) | Locals buffer
64 ---------------------------------------------------------------------
65 Source buffer | Input/Output (of debuggee) buffer
73 ---------------------------------------------------------------------
74 Stack buffer | Breakpoints buffer
75 \[mouse-2\] gdb-frames-select | SPC gdb-toggle-bp-this-line
76 | g gdb-goto-bp-this-line
77 | d gdb-delete-bp-this-line
78 ---------------------------------------------------------------------
80 All the buffers share the toolbar and source should always display in the same
81 window e.g after typing g on a breakpoint in the breakpoints buffer. Breakpoint
82 icons are displayed both by setting a break with gud-break and by typing break
85 Displayed expressions appear in separate frames. Arrays may be displayed
86 as slices and visualised using the graph program from plotutils if installed.
88 If `gdb-many-windows' is set to nil then gdb starts with just two windows :
89 the GUD and the source buffer.
91 The following interactive lisp functions help control operation :
93 `gdb-many-windows' - Toggle the number of windows gdb uses.
94 `gdb-restore-windows' - to restore the layout if its lost.
95 `gdb-quit' - to delete (most) of the buffers used by gdb."
