| general valgrind monitor commands: |
| help [debug] : monitor command help. With debug: + debugging commands |
| v.wait [<ms>] : sleep <ms> (default 0) then continue |
| v.info all_errors : show all errors found so far |
| v.info last_error : show last error found |
| v.info location <addr> : show information about location <addr> |
| v.info n_errs_found [msg] : show the nr of errors found so far and the given msg |
| v.info open_fds : show open file descriptors (only if --track-fds=yes) |
| v.kill : kill the Valgrind process |
| v.set gdb_output : set valgrind output to gdb |
| v.set log_output : set valgrind output to log |
| v.set mixed_output : set valgrind output to log, interactive output to gdb |
| v.set merge-recursive-frames <num> : merge recursive calls in max <num> frames |
| v.set vgdb-error <errornr> : debug me at error >= <errornr> |

| memcheck monitor commands: |
| get_vbits <addr> [<len>] |
| returns validity bits for <len> (or 1) bytes at <addr> |
| bit values 0 = valid, 1 = invalid, __ = unaddressable byte |
| Example: get_vbits 0x........ 10 |
| make_memory [noaccess|undefined |
| |defined|Definedifaddressable] <addr> [<len>] |
| mark <len> (or 1) bytes at <addr> with the given accessibility |
| check_memory [addressable|defined] <addr> [<len>] |
| check that <len> (or 1) bytes at <addr> have the given accessibility |
| and outputs a description of <addr> |

| [heuristics heur1,heur2,...] |

| Examples: leak_check |
| leak_check summary any |
| leak_check full kinds indirect,possible |
| leak_check full reachable any limited 100 |
| block_list <loss_record_nr> |
| after a leak search, shows the list of blocks of <loss_record_nr> |
| who_points_at <addr> [<len>] |
| shows places pointing inside <len> (default 1) bytes at <addr> |
| (with len 1, only shows "start pointers" pointing exactly to <addr>, |
| with len > 1, will also show "interior pointers") |
