There are several other commands to print information about the selected stack frame:
- frame or f
-
When used without any argument, this command doesn't change which
frame is selected, but prints a brief description of the currently
selected stack frame.
It can be abbreviated f.
With an argument, this command is used to select a stack frame.
See Selecting a frame.
- info frame or info f
-
This command prints a verbose description of the selected stack frame, including:
- the address of the frame
- the address of the next frame down (called by this frame)
- the address of the next frame up (caller of this frame)
- the language in which the source code corresponding to this frame is written
- the address of the frame's arguments
- the program counter saved in it (the address of execution in the caller frame)
- which registers were saved in the frame
The verbose description is useful when something has gone wrong that has made the stack format fail to fit
the usual conventions.
- info frame addr or
info f addr
- Print a verbose description of the frame at address addr, without selecting that frame.
The selected frame remains unchanged by this command.
This requires the same kind of address (more than one for some
architectures) that you specify in the frame command.
See Selecting a frame.
- info args
-
Print the arguments of the selected frame, each on a separate line.
- info locals
-
Print the local variables of the selected frame, each on a separate line.
These are all variables (declared either static or automatic)
accessible at the point of execution of the selected frame.
- info catch
-
Print a list of all the exception handlers that are active in the
current stack frame at the current point of execution. To see other
exception handlers, visit the associated frame (using the up,
down, or frame commands); then type
info catch.
See Breakpoints and exceptions.
