# valgrind
|
|
|
|
> Wrapper for a set of expert tools for profiling, optimizing, and debugging programs.
|
|
> Commonly used tools include `memcheck`, `cachegrind`, `callgrind`, `massif`, `helgrind`, and `drd`.
|
|
> More information: <https://valgrind.org/docs/manual/manual-core.html#manual-core.options>.

|
|
|
- Use the (default) Memcheck tool to show a diagnostic of memory usage by `program`:
|
|
|
|
`valgrind {{program}}`
|
|
|
|
- Use Memcheck to report all possible memory leaks of `program` in full detail:
|
|
|
|
`valgrind --leak-check=full --show-leak-kinds=all {{program}}`
|
|
|
|
- Use the Cachegrind tool to profile and log CPU cache operations of `program`:
|
|
|
|
`valgrind --tool=cachegrind {{program}}`
|
|
|
|
- Use the Massif tool to profile and log heap memory and stack usage of `program`:
|
|
|
|
`valgrind --tool=massif --stacks=yes {{program}}`
