## Function Documentation

## purple_global_proxy_get_info()

PurpleProxyInfo * purple_global_proxy_get_info | ( | void |  | ) |

Returns purple's global proxy information.

Returns
  The global proxy information.

## purple_global_proxy_set_info()

void purple_global_proxy_set_info | ( | PurpleProxyInfo * | info | ) |

Set purple's global proxy information.

Parameters

  info | The proxy information.

Since
  2.6.0

## purple_proxy_connect()

PurpleProxyConnectData * purple_proxy_connect | ( | void * | handle,
|  | PurpleAccount * | account,
|  | const char * | host,
|  | int | port,
|  | PurpleProxyConnectFunction | connect_cb,
|  | gpointer | data
| ) |  |

Makes a connection to the specified host and port.

Note that this function name can be misleading–although it is called "proxy connect," it is used for establishing any outgoing TCP connection, whether through a proxy or not.

Parameters

  handle | A handle that should be associated with this connection attempt. The handle can be used to cancel the connection attempt using the purple_proxy_connect_cancel_with_handle() function.
  account | The account making the connection.
  host | The destination host.
  port | The destination port.
  connect_cb | The function to call when the connection is established. If the connection failed then fd will be -1 and error message will be set to something descriptive (hopefully).
  data | User-defined data.

Returns
  NULL if there was an error, or a reference to an opaque data structure that can be used to cancel the pending connection, if needed.

## purple_proxy_connect_cancel()

void purple_proxy_connect_cancel | ( | PurpleProxyConnectData * | connect_data | ) |

Cancel an in-progress connection attempt.

This should be called by the PRPL if the user disables an account while it is still performing the initial sign on. Or when establishing a file transfer, if we attempt to connect to a remote user but they are behind a firewall then the PRPL can cancel the connection attempt early rather than just letting the OS's TCP/IP stack time-out the connection.

## purple_proxy_connect_socks5()

PurpleProxyConnectData * purple_proxy_connect_socks5 | ( | void * | handle,
|  | PurpleProxyInfo * | gpi,
|  | const char * | host,
|  | int | port,
|  | PurpleProxyConnectFunction | connect_cb,
|  | gpointer | data
| ) |  |

Makes a connection through a SOCKS5 proxy.

Parameters

  handle | A handle that should be associated with this connection attempt. The handle can be used to cancel the connection attempt using the purple_proxy_connect_cancel_with_handle() function.
  gpi | The PurpleProxyInfo specifying the proxy settings
  host | The destination host.
  port | The destination port.
  connect_cb | The function to call when the connection is established. If the connection failed then fd will be -1 and error message will be set to something descriptive (hopefully).
  data | User-defined data.

Returns
  NULL if there was an error, or a reference to an opaque data structure that can be used to cancel the pending connection, if needed.

Deprecated:
  Use purple_proxy_connect_socks5_account instead

## purple_proxy_connect_socks5_account()

PurpleProxyConnectData * purple_proxy_connect_socks5_account | ( | void * | handle,
|  | PurpleAccount * | account,
|  | PurpleProxyInfo * | gpi,
|  | const char * | host,
|  | int | port,
|  | PurpleProxyConnectFunction | connect_cb,
|  | gpointer | data
| ) |  |

Makes a connection through a SOCKS5 proxy.

Note that if the account that is making the connection uses a proxy, this connection to a SOCKS5 proxy will be made through the account proxy.

Parameters

  handle | A handle that should be associated with this connection attempt. The handle can be used to cancel the connection attempt using the purple_proxy_connect_cancel_with_handle() function.
  account | The account making the connection.
  gpi | The PurpleProxyInfo specifying the proxy settings
  host | The destination host.
  port | The destination port.
  connect_cb | The function to call when the connection is established. If the connection failed then fd will be -1 and error message will be set to something descriptive (hopefully).
  data | User-defined data.

Returns
  NULL if there was an error, or a reference to an opaque data structure that can be used to cancel the pending connection, if needed.

## purple_proxy_connect_udp()

PurpleProxyConnectData * purple_proxy_connect_udp | ( | void * | handle,
|  | PurpleAccount * | account,
|  | const char * | host,
|  | int | port,
|  | PurpleProxyConnectFunction | connect_cb,
|  | gpointer | data
| ) |  |

Makes a connection to the specified host and port.

Note that this function name can be misleading–although it is called "proxy connect," it is used for establishing any outgoing UDP connection, whether through a proxy or not.

  account | The account making the connection.
