Function iai_callgrind::client_requests::valgrind::count_errors

pub fn count_errors() -> usize

Available on crate feature client_requests_defs only.

Counts the number of errors that have been recorded by a tool.

Can be useful to eg. can send output to /dev/null and still count errors.

The tool must record the errors with VG_(maybe_record_error)() or VG_(unique_error)() for them to be counted. These are to my best knowledge (as of Valgrind 3.22) Memcheck, DRD and Helgrind.
