UnixSocketAddress - UNIX SocketAddress.
Support for UNIX-domain (also known as local) sockets.
UNIX domain sockets are generally visible in the filesystem. However, some systems support abstract socket names which are not visible in the filesystem and not affected by the filesystem permissions, visibility, etc. Currently this is only supported under Linux. If you attempt to use abstract sockets on other systems, function calls may return Gio::IO_ERROR_NOT_SUPPORTED errors. You can use Gio::UnixSocketAddress::abstract_names_supported() to see if abstract names are supported.
Note that <giomm/unixsocketaddress.h>
belongs to the UNIX-specific GIO interfaces.

Creates a new UnixSocketAddress for path.
To create abstract socket addresses, on systems that support that, use g_unix_socket_address_new_abstract().
path | The socket path. |
|
static |
Creates a new UnixSocketAddress of type type with name path.
If type is UNIX_SOCKET_ADDRESS_PATH, this is equivalent to calling g_unix_socket_address_new().
If path_type is UNIX_SOCKET_ADDRESS_ABSTRACT, then path_len bytes of path will be copied to the socket's path, and only those bytes will be considered part of the name. (If path_len is -1, then path is assumed to be NUL-terminated.) For example, if path was "test", then calling g_socket_address_get_native_size() on the returned socket would return 7 (2 bytes of overhead, 1 byte for the abstract-socket indicator byte, and 4 bytes for the name "test").
If path_type is UNIX_SOCKET_ADDRESS_ABSTRACT_PADDED, then path_len bytes of path will be copied to the socket's path, the rest of the path will be padded with 0 bytes, and the entire zero-padded buffer will be considered the name. (As above, if path_len is -1, then path is assumed to be NUL-terminated.) In this case, g_socket_address_get_native_size() will always return the full size of a struct sockaddr_un
, although g_unix_socket_address_get_path_len() will still return just the length of path.
UNIX_SOCKET_ADDRESS_ABSTRACT is preferred over UNIX_SOCKET_ADDRESS_ABSTRACT_PADDED for new programs. Of course, when connecting to a server created by another process, you must use the appropriate type corresponding to how that process created its listening socket.
path | The name. |
path_len | The length of path, or -1. |
type | A UnixSocketAddressType. |
UnixSocketAddressType Gio::UnixSocketAddress::get_address_type | ( | ) | const |
std::string Gio::UnixSocketAddress::get_path | ( | ) | const |
Gets address's path, or for abstract sockets the "name".
Guaranteed to be zero-terminated, but an abstract socket may contain embedded zeros, and thus you should use g_unix_socket_address_get_path_len() to get the true length of this string.
