/sys$common/syshlp/helplib.hlb TCPIP Services, Programming Interfaces, Sockets API, accept(), Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    This function completes the first connection on the queue
    of pending connections, creates a new socket with the same
    properties as s, and allocates and returns a new 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 request is present. If the
    socket is marked nonblocking by using a setsockopt() call and no
    pending connections are present on the queue, accept() returns
    an error. You cannot use the accepted socket to accept subsequent
    connections. The original socket s remains open (listening) for
    other connection requests. This call is used with connection-
    based socket types (SOCK_STREAM).
