#define n_log(__LEVEL__,...)
Logging function wrapper to get line and func.
#define LOG_DEBUG
debug-level messages
#define LOG_STDERR
internal, default LOG_TYPE
void set_log_level(const int log_level)
Set the global log level value ( static int LOG_LEVEL )
void set_signal_handler(const char *progname)
Install a signal handler for progname.
Signals general handling with stack printing, from https://gist.github.com/jvranish/4441299.
