LOCAL FUNCTION

SYNOPSIS
- void proc_info (char *args, int from_tty)
+ void info_proc (char *args, int from_tty)
DESCRIPTION
Examples of the use of "info proc" are:
- info proc Print short info about current inferior.
- info proc verbose Print verbose info about current inferior.
- info proc 123 Print short info about process pid 123.
- info proc 123 verbose Print verbose info about process pid 123.
+ info proc (prints summary info for current inferior)
+ info proc 123 (prints summary info for process with pid 123)
+ info proc mappings (prints address mappings)
+ info proc times (prints process/children times)
+ info proc id (prints pid, ppid, gid, sid, etc)
+ info proc status (prints general process state info)
+ info proc signals (prints info about signal handling)
+ info proc all (prints all info)
