Display and Control Commands

The following commands display and control the status of adb(1)/ kadb(1M):


Display all breakpoints 


Display stack trace 


Change default radix to value of dot 




Display registers 


Display built-in macros 

`$c' is useful with crash dumps: it shows the call trace and arguments at the time of the crash. It is also useful in kadb(1M) when a breakpoint is reached, but is usually not useful if kadb(1M) is entered at a random time. The number of arguments to print can be passed following the `$c' (`$c 2' for two arguments).
