Predefined dbx Variables
Variable
Default
Description
$showbreakaddrs
0
If nonzero, show the address of each
breakpoint placed in the code each time it is
placed. Removal of the breakpoints is not
shown. If multiple breakpoints are placed at
one location, only one of the placements is
shown. Since breakpoints are frequently
placed and removed by dbx, the volume of
output can be annoying when tracing.
$stacktracelimit
$stepintoall
Limits to the depth of the stack trace.
0
If 0, step steps into only those procedures that
are compiled with the debugging option -g.
step steps over all other procedures.
If 1 or 2, step steps into all procedures. Note
that when you debug a source file compiled
without symbols or compiled with
optimization, the line numbers may
sometimes jump erratically.
Also note that if dbx cannot locate a source file,
then it cannot display source lines as you step
through a procedure.
$tagfile
tags
The name of a file of tags, as created by
ctags(1). Used by the tag command.
