Kgio::UNIXServer

Initiates a blocking accept and returns a generic Kgio::Socket object with the kgio_addr attribute set (to the value of Kgio::LOCALHOST) on success.

On Ruby implementations using native threads, this can use a blocking accept(2) (or accept4(2)) system call to avoid thundering herds.

An optional class argument may be specified to override the Kgio::Socket-class return value:

server.kgio_accept(MySocket) -> MySocket

static VALUE unix_accept(int argc, VALUE *argv, VALUE io)
{
        VALUE klass = acceptor(argc, argv);
        VALUE rv = my_accept(io, klass, NULL, NULL, 0);

        rb_ivar_set(rv, iv_kgio_addr, localhost);
        return rv;
}

Initiates a non-blocking accept and returns a generic Kgio::Socket object with the kgio_addr attribute set (to the value of Kgio::LOCALHOST) on success.

Returns nil on EAGAIN, and raises on other errors.

An optional class argument may be specified to override the Kgio::Socket-class return value:

server.kgio_tryaccept(MySocket) -> MySocket

static VALUE unix_tryaccept(int argc, VALUE *argv, VALUE io)
{
        VALUE klass = acceptor(argc, argv);
        VALUE rv = my_accept(io, klass, NULL, NULL, 1);

        if (!NIL_P(rv))
                rb_ivar_set(rv, iv_kgio_addr, localhost);
        return rv;
}
