if i want to attach the valgrind for more than one process at the same time what is the command/option to use.
There is no such command or option. Each valgrind tool applies to only one process. The closest you can come is to invoke each process using a (separate) valgrind tool. _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
