TIMEOUTGETADDRINFO(3) TIMEOUTGETADDRINFO(3) NAME timeoutgetaddrinfo - getaddrinfo with a time out SYNOPSIS #include int timeoutgetaddrinfo(const char *node, const char *service, struct addrinfo *hints, struct addrinfo ** res, long long timeout); DESCRIPTION Works just like getaddrinfo (3) except timeoutgetaddrinfo will return with an error if it takes longer the timeout milliseconds to complete. Avoid setting the timeout under 5 seconds (5000 ms). Note that timeoutgetaddrinfo() works by calling getaddrinfo_a(), a GNU libc extension. getaddrinfo_a, in turn, spawns a thread which does a blocking getaddrinfo(). Because that thread is not guaranteed to com- plete in a timely manner, it will continue even after timeoutgetad- drinfo() returns due to a time out. Resources allocated to that thread will be cleaned up in by later call to timeoutgetaddrinfo() or when the program overall ends. See getaddrinfo (3) for more.
