## Function Documentation

## ◆ _dbus_server_listen_socket()

DBusServerListenResult _dbus_server_listen_socket | ( | DBusAddressEntry * | entry,
|  | DBusServer ** | server_p,
|  | DBusError * | error
| ) |  |

Tries to interpret the address entry for various socket-related addresses (well, currently only tcp and nonce-tcp).

Sets error if the result is not OK.

Parameters

  entry | an address entry
  server_p | a new DBusServer, or NULL on failure.
  error | location to store rationale for failure on bad address

Returns
  the outcome

## ◆ _dbus_server_new_for_socket()

DBusServer* _dbus_server_new_for_socket | ( | DBusSocket * | fds,
|  | int | n_fds,
|  | const DBusString * | address,
|  | DBusNonceFile * | noncefile,
|  | DBusError * | error
| ) |  |

Creates a new server listening on the given file descriptor.

The file descriptor should be nonblocking (use _dbus_set_fd_nonblocking() to make it so). The file descriptor should be listening for connections, that is, listen() should have been successfully invoked on it. The server will use accept() to accept new client connections.

Parameters

  fds | list of file descriptors.
  n_fds | number of file descriptors
  address | the server's address
  noncefile | to be used for authentication (NULL if not needed)
  error | location to store reason for failure

Returns
  the new server, or NULL on OOM or other error.

## ◆ _dbus_server_new_for_tcp_socket()

DBusServer* _dbus_server_new_for_tcp_socket | ( | const char * | host,
|  | const char * | bind,
|  | const char * | port,
|  | const char * | family,
|  | DBusError * | error,
|  | dbus_bool_t | use_nonce
| ) |  |

Creates a new server listening on TCP.

If host is NULL, it will default to localhost. If bind is NULL, it will default to the value for the host parameter, and if that is NULL, then localhost If bind is a hostname, it will be resolved and will listen on all returned addresses. If family is NULL, hostname resolution will try all address families, otherwise it can be ipv4 or ipv6 to restrict the addresses considered.

Parameters

  host | the hostname to report for the listen address
  bind | the hostname to listen on
  port | the port to listen on or 0 to let the OS choose
  family |
  error | location to store reason for failure.
  use_nonce | whether to use a nonce for low-level authentication (nonce-tcp transport) or not (tcp transport)

Returns
  the new server, or NULL on failure.

## ◆ _dbus_server_socket_own_filename()

void _dbus_server_socket_own_filename | ( | DBusServer * | server,
|  | char * | filename
| ) |  |

This is a bad hack since it's really unix domain socket specific.

Also, the function weirdly adopts ownership of the passed-in string.

Parameters

  server | a socket server
  filename | socket filename to report/delete
