pub fn on_error_stack_trace(prg_name: Option<&str>)Expand description
Invokes gdb, which attaches to the current process and shows a stack trace. Called by g_on_error_query() when the “[S]tack trace” option is selected. You can get the current process’s program name with g_get_prgname(), assuming that you have called gtk_init() or gdk_init().
This function may cause different actions on non-UNIX platforms.
When running on Windows, this function is not called by
g_on_error_query(). If called directly, it will raise an
exception, which will crash the program. If the G_DEBUGGER environment
variable is set, a debugger will be invoked to attach and
handle that exception (see Running GLib Applications).
§prg_name
the program name, needed by gdb for the
“[S]tack trace” option, or NULL to use a default string
