This may be used to determine whether it is safe to call the backtrace functions from a signal handler. In general this only applies to calls like backtrace and backtrace_pcinfo. It does not apply to backtrace_simple, which never calls malloc. It does not apply to backtrace_print, which always calls fprintf and therefore malloc. */ #define BACKTRACE_USES_MALLOC 0 /* BACKTRACE_SUPPORTS_THREADS will be #define'd as 1 if the backtrace library is configured with threading support, 0 if not.
