Function Documentation

◆dbus_address_entries_free()

DBUS_EXPORT void dbus_address_entries_free	(	DBusAddressEntry **	entries	)

Frees a NULL-terminated array of address entries.

释放以NULL结尾的地址项数组。

• Parameters

  ​ entries the array.

Definition at line 192 of file dbus-address.c.

References dbus_free(), and NULL.

◆dbus_address_entry_get_method()

const DBUS_EXPORT char * dbus_address_entry_get_method	(	DBusAddressEntry *	entry	)

Returns the method string of an address entry.

For example, given the address entry "tcp:host=example.com" it would return the string "tcp"

返回地址项的方法字符串。

例如，给定地址项目“ tcp：host = example.com”，它将返回字符串“ tcp”

• Parameters

  ​ entry the entry.

• Returns

  a string describing the method. This string must not be freed.

Definition at line 230 of file dbus-address.c.

References DBusAddressEntry::method.

Referenced by _dbus_server_listen_platform_specific(), _dbus_server_listen_socket(), _dbus_transport_open_platform_specific(), and _dbus_transport_open_socket().

◆dbus_address_entry_get_value()

const DBUS_EXPORT char * dbus_address_entry_get_value	(	DBusAddressEntry *	entry,
		const char *	key
	)

Returns a value from a key of an entry.

For example, given the address "tcp:host=example.com,port=8073" if you asked for the key "host" you would get the value "example.com"

The returned value is already unescaped.

从条目的键返回对应的值。

例如，给定地址“ tcp：host = example.com，port = 8073”，如果您要求键“ host”，则将获得值“ example.com”

返回的值已经被转义。

• Parameters

  ​ entry the entry.

  ​ key the key.

• Returns

  the key value. This string must not be freed.

◆dbus_address_escape_value()

DBUS_EXPORT char * dbus_address_escape_value	(	const char *	value	)

Escapes the given string as a value in a key=value pair for a D-Bus address.

将给定的字符串转义为D-Bus地址的键=值对中的值。

• Parameters

  ​ value the unescaped value

• Returns

  newly-allocated escaped value or NULL if no memory

Definition at line 586 of file dbus-address.c.

References _dbus_address_append_escaped(), _dbus_string_free(), _dbus_string_init(), _dbus_string_init_const(), _dbus_string_steal_data(), and NULL.

◆dbus_address_unescape_value()

DBUS_EXPORT char * dbus_address_unescape_value	(	const char *	value,
		DBusError *	error
	)

Unescapes the given string as a value in a key=value pair for a D-Bus address.

Note that dbus_address_entry_get_value() returns an already-unescaped value.

将给定的字符串取消转义为D-Bus地址的key = value对中的值。

请注意，dbus_address_entry_get_value（）返回一个已经转义的值。

• Parameters

  ​ value the escaped value

  ​ error error to set if the unescaping fails

• Returns

  newly-allocated unescaped value or NULL if no memory

Definition at line 620 of file dbus-address.c.

References _dbus_string_init(), _dbus_string_init_const(), and NULL.

◆dbus_parse_address()

DBUS_EXPORT dbus_bool_t dbus_parse_address	(	const char *	address,
		DBusAddressEntry ***	entry_result,
		int *	array_len,
		DBusError *	error
	)

Parses an address string of the form:

method:key=value,key=value;method:key=value

See the D-Bus specification for complete docs on the format.

When connecting to an address, the first address entries in the semicolon-separated list should be tried first.

解析以下形式的地址字符串：

method:key=value,key=value;method:key=value

有关格式的完整文档，请参见D-Bus规范。

连接到地址时，应首先尝试以分号分隔的列表中的第一个地址条目。

• Parameters

  address	the address.
  entry_result	return location to an array of entries.
  array_len	return location for array length.
  error	address where an error can be returned.

• Returns

  TRUE on success, FALSE otherwise.
