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 n_errs_found : show the nr of errors found so far
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 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>
leak_check [full*|summary] [reachable|possibleleak*|definiteleak]
[increased*|changed|any]
[unlimited*|limited <max_loss_records_output>]
* = defaults
Examples: leak_check
leak_check summary any
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")

debugging valgrind internals monitor commands:
v.info gdbserver_status : show gdbserver status
v.info memory [aspacemgr] : show valgrind heap memory stats
(with aspacemgr arg, also shows valgrind segments on log ouput)
v.info scheduler : show valgrind thread state and stacktrace
v.set debuglog <level> : set valgrind debug log level to <level>
v.translate <addr> [<traceflags>] : debug translation of <addr> with <traceflags>
(default traceflags 0b00100000 : show after instrumentation)
An additional flag 0b100000000 allows to show gdbserver instrumentation
