accept (2N) accept (2N) NAME accept - accept a connection on a socket SYNOPSIS *include *include int accept (s, addr, addrlen) int S; struct sockaddr *addr; int *addrlen; DESCRIPTION The argument s is a socket which has been created with socket(2N), bound to an address with bind(2N), and is listening for connections after a listen(2N). accept extracts the first connection on the queue of pending connections, creates a new socket with the same properties of s and allocates a new file descriptor for the socket. If no pending connections are present on the queue, and the socket is not marked as nonblocking, accept blocks the caller until a connection is present. If the socket is marked nonblocking and no pending connections are present on the queue, accept returns an error as described below. The accepted socket may not be used to accept more connections. The original socket s remains open. The argument addr is a result parameter which is filled in with the address of the connecting entity, as known to the communications layer. The exact format of the addr parameter is determined by the domain in which the communication is occurring. The addrlen is a value-result parameter; it should initially contain the amount of space pointed to by addr; on return it will contain the actual length (in bytes) of the address returned. This call is used with connection-based socket types, currently with SOCK STREAM. It is possible to select(2N) a socket for the purposes of doing an accept by selecting it for read. RETURN VALUE The call returns -Ion error. If it succeeds it returns a nonnegative integer which is a descriptor for the accepted socket. 1 February, 1990 Revision C
accept(2N) ERRORS accept will fail if: [EBADF] [ENOTSOCK] [EOPNOTSUPP] [EFAULT] [EWOULDBLOCK] The descriptor is invalid. accept(2N) The descriptor references a file, not a socket. The referenced socket is not of type SOCK STREAM. The addr parameter is not in a writable part of the user address space. The socket is marked nonblocking and no connections are present to be accepted. SEE ALSO bind(2N), connect(2N), listen(2N), select(2N), socket(2N). February, 1990 2 Revision C
