accept - accepts incoming connections on a socket #include <sys/socket.h> int accept(int sd, struct sockaddr * addr, socklen_t * addr_len);

accept() accepts a new incoming connection on a listening socket sd. The structure pointed to by addr is filled in with the address of the peer, and addr_len is set to the length of the address of the peer. On success, this function returns a numeric socket descriptor. On error, -1 is returned and errno is set.

15 [EOPNOTSUPP] The socket does not support accept(2) (example: a UDP socket).

15 [ENOTSOCK] The sd argument is not a socket.

15 [EINVAL] The socket is not listening or in an invalid state.
