WebJan 21, 2024 · FD_ISSET(fd, &fdset) is non-zero if fd is a member of fdset, zero otherwise. The behavior of these macros is undefined if a descriptor value is less than zero or greater than or equal to FD_SETSIZE , which is normally at least equal to the maximum number of descriptors supported by the system.
