1usage: valgrind [options] prog-and-args 2 3 tool-selection option, with default in [ ]: 4 --tool=<name> use the Valgrind tool named <name> [memcheck] 5 6 basic user options for all Valgrind tools, with defaults in [ ]: 7 -h --help show this message 8 --help-debug show this message, plus debugging options 9 --version show version 10 -q --quiet run silently; only print error msgs 11 -v --verbose be more verbose -- show misc extra info 12 --trace-children=no|yes Valgrind-ise child processes (follow execve)? [no] 13 --trace-children-skip=patt1,patt2,... specifies a list of executables 14 that --trace-children=yes should not trace into 15 --trace-children-skip-by-arg=patt1,patt2,... same as --trace-children-skip= 16 but check the argv[] entries for children, rather 17 than the exe name, to make a follow/no-follow decision 18 --child-silent-after-fork=no|yes omit child output between fork & exec? [no] 19 --vgdb=no|yes|full activate gdbserver? [yes] 20 full is slower but provides precise watchpoint/step 21 --vgdb-error=<number> invoke gdbserver after <number> errors [999999999] 22 to get started quickly, use --vgdb-error=0 23 and follow the on-screen directions 24 --track-fds=no|yes track open file descriptors? [no] 25 --time-stamp=no|yes add timestamps to log messages?
