<H3>SYNOPSIS</H3>

|
|
*<VAR>addrlen</VAR>);</CODE>

<H3>PARAMETERS</H3>
|
|
<P>
|
|
<VAR>s</VAR>: [in] the socket connections are accepted from.
|
|
<P>
|
|
<VAR>addr</VAR>: [out] contains the address of the the buffer that will be
|
|
filled with the address of connecting entity.
|
|
<P>
|
|
<VAR>addrlen</VAR>: [out] on input contains the maximum length of addr in
|
|
bytes, on output contains the length of addr in bytes.
|
|
<P>
|
|
<H3>DESCRIPTION</H3>
|
|
<P>
|
|
If connections are pending on the socket <VAR>s</VAR>, the first connection
|
|
in the queue is dequeued and opened and a new socket with the same
|
|
properties of <VAR>s</VAR> is returned. If no connection is pending and the
|
|
socket is blocking, then the call blocks until a connection is requested
|
|
on <VAR>s</VAR>. Otherwise the call returns an error code. The socket <VAR>s</VAR>
|
|
remains open for future connections. The address of the connecting
|
|
entity is returned in <VAR>addr</VAR>. The format of the address depends on
|
|
the type of network on through which the socket communicates.
|
|
<CODE>accept</CODE> does not send a confirmation at the connecting entity.
|
|
<P>
|
|
<H3>RETURN VALUE</H3>
|
|
<P>
|
|
On success, the call returns a positive value that is the file
|
|
descriptor of the new socket. On errror, the call returns -1 and sets
|
|
<CODE>errno</CODE> to one of the following error values:
|
|
<P>
|
|
<UL>
|
|
<LI><CODE>EOPNOTSUPP</CODE>: The referenced socket is not of type
|
|
<CODE>SOCK_STREAM</CODE>.
|
|
<LI><CODE>EWOULDBLOCK</CODE>: The socket is marked non-blocking and no
|
|
connection is pending.
|
|
<LI><CODE>EBADF</CODE>, <CODE>ENOTSOCK</CODE> or <CODE>EFAULT</CODE>
|
|
</UL>
