@ -2040,9 +2040,12 @@ void qErrnoWarning(int code, const char *msg, ...)
\row \li \c{%{backtrace [depth=N] [separator="..."]}} \li A backtrace with the number of frames
specified by the optional \c depth parameter (defaults to 5), and separated by the optional
\c separator parameter (defaults to "|").
This expansion is available only on some platforms (currently only platfoms using glibc).
Names are only known for exported functions. If you want to see the name of every function
in your application, use \c{QMAKE_LFLAGS += -rdynamic}.
in your application, make sure your application is compiled and linked with \c{-rdynamic},
or an equivalent of it.
When reading backtraces, take into account that frames might be missing due to inlining or
tail call optimization.
