g_on_error_stack_trace (
  const gchar* prg_name


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 const gchar*

The program name, needed by gdb for the “[S]tack trace” option.

 The data is owned by the caller of the function.
 The value is a NUL terminated UTF-8 string.
