<p>
|
||||
<b>Description:</b>
|
||||
To accept connections, a socket is first created with <code>socket()</code>, a
|
||||
willingness to accept incoming connections and a queue limit for incoming
|
||||
connections are specified with <code>listen()</code>, and then the connections are
|
||||
accepted with <code>accept()</code>. The <code>listen()</coe> call applies only to sockets of
|
||||
type <code>SOCK_STREAM</code> or <code>SOCK_SEQPACKET</code>.
|
||||
</p>
|
||||
<p>
|
||||
<b>Input Parameters:</b>
|
||||
</p>
|
||||
<ul>
|
||||
<li><code>sockfd</code>: Socket descriptor of the bound socket.</li>
|
||||
<li><code>backlog</code>: The maximum length the queue of pending connections may grow.
|
||||
If a connection request arrives with the queue full, the client may receive an error
|
||||
with an indication of ECONNREFUSED or, if the underlying protocol supports retransmission,
|
||||
the request may be ignored so that retries succeed.</li>
|
||||
</ul>
|
||||
<p>
|
||||
<b>Returned Values:</b>
|
||||
On success, zero is returned. On error, -1 is returned, and errno is set appropriately.
|
||||
</p>
|
||||
<ul>
|
||||
<li><code>EADDRINUSE</code>: Another socket is already listening on the same port.</li>
|
||||
<li><code>EBADF</code>: The argument <code>sockfd</code> is not a valid descriptor.</li>
|
||||
<li><code>ENOTSOCK</code>: The argument <code>sockfd</code> is not a socket.</li>
|
||||
<li><code>EOPNOTSUPP</code>: The socket is not of a type that supports the listen operation.</li>

<p>

<b>Function Prototype:</b>
|
||||
</p>
|
||||
<pre>
|
||||
#include <sys/socket.h>
|
||||
int accept(int sockfd, struct sockaddr *addr, socklen_t *addrlen);
|
||||
</pre>
|
||||
<p>
|
||||
<b>Description:</b>
|
||||
The <code>accept()</code> function is used with connection-based socket types
|
||||
(<code>SOCK_STREAM</code>, <code>SOCK_SEQPACKET</code> and <code>SOCK_RDM</code>).
|
||||
It extracts the first connection request on the queue of pending connections,
|
||||
creates a new connected socket with most of the same properties as <code>sockfd</code>,
|
||||
and allocates a new socket descriptor for the socket, which is returned. The
|
||||
newly created socket is no longer in the listening state. The original
|
||||
socket <code>sockfd</code> is unaffected by this call. Per file descriptor flags
|
||||
are not inherited across an accept.
|
||||
</p>
|
||||
<p>
|
||||
The <code>sockfd</code> argument is a socket descriptor that has been created with
|
||||
<code>socket()</code>, bound to a local address with <code>bind()</code>, and is listening for
|
||||
connections after a call to <code>listen()</code>.
|
||||
</p>
|
||||
<p>
|
||||
On return, the <code>addr</code> structure is filled in with the address of the
|
||||
connecting entity. The <code>addrlen</code> argument initially contains the size
|
||||
of the structure pointed to by <code>addr</code>; on return it will contain the
|
||||
actual length of the address returned.
|
||||
</p>
|
||||
<p>
|
||||
If no pending connections are present on the queue, and the socket is
|
||||
not marked as non-blocking, accept blocks the caller until a connection
|
||||
is present. If the socket is marked non-blocking and no pending
|
||||
connections are present on the queue, accept returns <code>EAGAIN</code>.
|
||||
</p>
|
||||
<p>
|
||||
<b>Input Parameters:</b>
|
||||
</p>
|
||||
<ul>
|
||||
<li><code>sockfd</code>: Socket descriptor of the listening socket.</li>
|
||||
<li><code>addr</code>: Receives the address of the connecting client.</li>
|
||||
<li><code>addrlen</code>: Input: allocated size of <code>addr</code>, Return: returned size of <code>addr</code>.</li>
|
||||
</ul>
|
||||
<p>
|
||||
<b>Returned Values:</b>
|
||||
Returns -1 on error. If it succeeds, it returns a non-negative integer
|
||||
that is a descriptor for the accepted socket.
|
||||
</p>
|
||||
<ul>
|
||||
<li><code>EAGAIN</code> or <code>EWOULDBLOCK</code>:
|
||||
The socket is marked non-blocking and no connections are present to be accepted.</li>
|
||||
<li><code>EBADF</code>:
|
||||
The descriptor is invalid.</li>
|
||||
<li><code>ENOTSOCK</code>:
|
||||
The descriptor references a file, not a socket.</li>
|
||||
<li><code>EOPNOTSUPP</code>:
|
||||
The referenced socket is not of type <code>SOCK_STREAM</code>.</li>
|
||||
<li><code>EINTR</code>:
|
||||
The system call was interrupted by a signal that was caught before a valid connection arrived.</li>
|
||||
<li><code>ECONNABORTED</code>:
|
||||
A connection has been aborted.</li>
|
||||
<li><code>EINVAL</code>:
|
||||
Socket is not listening for connections.</li>
|
||||
<li><code>EMFILE</code>:
|
||||
The per-process limit of open file descriptors has been reached.</li>
|
||||
<li><code>ENFILE</code>:
|
||||
The system maximum for file descriptors has been reached.</li>
|
||||
<li><code>EFAULT</code>:
|
||||
The addr parameter is not in a writable part of the user address space.</li>
|
||||
<li><code>ENOBUFS</code> or <code>ENOMEM</code>:
|
||||
Not enough free memory.</li>
|
||||
<li><code>EPROTO</code>:

||||
Protocol error.</li>

* a valid connection arrived.
|

* ECONNABORTED
|

* A connection has been aborted.
|
||||
* EINVAL
|

* Socket is not listening for connections.
|

* EMFILE
|

* ENFILE
|

* EFAULT
|

* Function: listen
|
||||
*
|
||||
* Description:
|
||||
* To accept connections, a socket is first created with socket(), a
|
||||
* willingness to accept incoming connections and a queue limit for incoming
|
||||
* connections are specified with listen, and then the connections are
|
||||
* accepted with accept(). The listen() call applies only to sockets of
|
||||
* type SOCK_STREAM or SOCK_SEQPACKET.
|
||||
*
|
||||
* Parameters:
|
||||
* sockfd Socket descriptor of the bound socket
|
||||
* backlog The maximum length the queue of pending connections may grow.
|
||||
* If a connection request arrives with the queue full, the client
|
||||
* may receive an error with an indication of ECONNREFUSED or,
|
||||
* if the underlying protocol supports retransmission, the request
|
||||
* may be ignored so that retries succeed.
|
||||
*
|
||||
* Returned Value:
|
||||
* On success, zero is returned. On error, -1 is returned, and errno is set
|
||||
* appropriately.
|
||||
*
|
||||
* EADDRINUSE
|
||||
* Another socket is already listening on the same port.
|
||||
* EBADF
|
||||
* The argument 'sockfd' is not a valid descriptor.
|
||||
* ENOTSOCK
|
||||
* The argument 'sockfd' is not a socket.
|
||||
* EOPNOTSUPP
|
||||
* The socket is not of a type that supports the listen operation.
