Macro print_stacktrace 

macro_rules! print_stacktrace {
    ($($arg:tt)+) => { ... };
}

Prints formatted text to the Valgrind output channel with a stack trace.

This macro wraps the C client request VALGRIND_PRINTF_BACKTRACE. It behaves similarly to std::println in terms of syntax, accepting a format string and a list of arguments.

Mechanics

The formatted string is sent to the Valgrind log. Immediately following the message, Valgrind prints the current stack trace (backtrace) to the same log.

Note: If the process runs without Valgrind, this macro does nothing (it is a no-op). No message or stack trace is generated.

Note

Requires Valgrind 3.0 or higher.
