35 * g_on_error_query() will prompt the user to either
36 * [E]xit, [H]alt, [P]roceed or show [S]tack trace.
37 * g_on_error_stack_trace() invokes gdb, which attaches to the current
38 * process and shows a stack trace.
39 * These function may cause different actions on non-unix platforms.
40 * The prg_name arg is required by gdb to find the executable, if it is
41 * passed as NULL, g_on_error_query() will try g_get_prgname().

47 * Actual use is strongly deprecated of course ;)
