ARES_THREADSAFETY(3) Library Functions Manual ARES_THREADSAFETY(3) NAME ares_threadsafety - Query if c-ares was built with thread-safety SYNOPSIS #include <ares.h> ares_bool_t ares_threadsafety(void); DESCRIPTION The ares_threadsafety(3) function returns if the library was built with thread safety enabled or not. As of c-ares 1.23.0, this simply means that every public function which references an ares_channel_t object will lock the channel on entry and re- lease the lock on exit of the function. This will prevent concurrent thread access to the channel, thus ensuring no corruption can occur. As of c-ares 1.26.0, this also indicates if ARES_OPT_EVENT_THREAD can be passed to ares_init_options(3). RETURN VALUES ares_threadsafety(3) can return any of the following values: ARES_TRUE Built with thread safety. ARES_FALSE Built without thread safety AVAILABILITY This function was first introduced in c-ares version 1.23.0.
