Description

NAME="AEN40854"

><CODE
><CODE
CLASS="FUNCDEF"
>int accept_connect</CODE
> (int socket)</CODE
></DIV
> After the socket <TT
CLASS="parameter"
>socket</TT
> has been created
using <A
HREF="get_example.php3?Function=socket"
>socket()</A
>, bound to a name with
<A
HREF="get_example.php3?Function=bind"
>bind()</A
>, and told to listen for connections
with <A
HREF="get_example.php3?Function=listen"
>listen()</A
>, this function will accept
incoming connections on that socket. Once a successful connection
is made, a new socket descriptor is returned, which may be used
for communication. If there are multiple connections queued on
the socket, the first will be used. If there are no pending
connections, accept_connect() will block until
a connection becomes present. If <TT
CLASS="parameter"
>socket</TT
>
has been made non-blocking using
<A
HREF="get_example.php3?Function=socket-set-blocking"
>socket_set_blocking()</A
> or
set_nonblock(), an error code will be
returned.
 The socket descriptor returned by
accept_connect() may not be used to accept new
connections. The original listening socket
<TT
CLASS="parameter"
>socket</TT
>, however, remains open and may be
reused.
 Returns a new socket descriptor on success, or a negative error
code on failure. This code may be passed to
<A
HREF="get_example.php3?Function=strerror"
>strerror()</A
> to get a textual explanation of the
error.
