30 * This is called from sys/select.h and sys/time.h for the common prototype
31 * of select(). Setting _DARWIN_C_SOURCE or _DARWIN_UNLIMITED_SELECT uses
32 * the version of select() that does not place a limit on the first argument
33 * (nfds). In the UNIX conformance case, values of nfds greater than
34 * FD_SETSIZE will return an error of EINVAL.
