945 | BUS is either the symbol `:system' or the symbol `:session'. | |
946 | ||
947 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |
948 | object path SERVICE is registered at. INTERFACE is an interface | |
949 | offered by SERVICE. It must provide METHOD. | |
950 | ||
951 | HANDLER is a Lisp function, which is called when the corresponding | |
952 | return message has arrived. | |
953 | ||
954 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
955 | specifies the maximun number of milliseconds the method call must | |
956 | return. The default value is 25.000. If the method call doesn't | |
957 | return in time, a D-Bus error is raised. | |
958 | ||
959 | All other arguments ARGS are passed to METHOD as arguments. They are | |
960 | converted into D-Bus types via the following rules: | |
961 | ||
962 | t and nil => DBUS_TYPE_BOOLEAN | |
963 | number => DBUS_TYPE_UINT32 | |
964 | integer => DBUS_TYPE_INT32 | |

967 | list => DBUS_TYPE_ARRAY | |
968 | ||
969 | All arguments can be preceded by a type symbol. For details about | |
970 | type symbols, see Info node `(dbus)Type Conversion'. | |
971 | ||
972 | The function returns a key into the hash table | |
973 | `dbus-registered-functions-table'. The corresponding entry in the | |
974 | hash table is removed, when the return message has been arrived, and | |

1584 | BUS is either the symbol `:system' or the symbol `:session'. | |
1585 | ||
39abdd4a MA |
1586 | SERVICE is the D-Bus service name used by the sending D-Bus object. |
1587 | It can be either a known name or the unique name of the D-Bus object | |
1588 | sending the signal. When SERVICE is nil, related signals from all | |
1589 | D-Bus objects shall be accepted. | |
033b73e2 | 1590 | |
39abdd4a MA |
1591 | PATH is the D-Bus object path SERVICE is registered. It can also be |
1592 | nil if the path name of incoming signals shall not be checked. | |
033b73e2 | 1593 | |
39abdd4a MA |
1594 | INTERFACE is an interface offered by SERVICE. It must provide SIGNAL. |
1595 | HANDLER is a Lisp function to be called when the signal is received. | |
944cc4a8 MA |
1596 | It must accept as arguments the values SIGNAL is sending. |
1597 | ||
1598 | All other arguments ARGS, if specified, must be strings. They stand | |
1599 | for the respective arguments of the signal in their order, and are | |
1600 | used for filtering as well. A nil argument might be used to preserve | |
1601 | the order. | |
1602 | ||
1603 | INTERFACE, SIGNAL and HANDLER must not be nil. Example: | |
033b73e2 MA |
1604 | |
1605 | \(defun my-signal-handler (device) | |
1606 | (message "Device %s added" device)) | |
1607 | ||
1608 | \(dbus-register-signal | |
52da95fa MA |
1609 | :system "org.freedesktop.Hal" "/org/freedesktop/Hal/Manager" |
1610 | "org.freedesktop.Hal.Manager" "DeviceAdded" 'my-signal-handler) | |
033b73e2 | 1611 | |
f5306ca3 MA |
1612 | => ((:system "org.freedesktop.Hal.Manager" "DeviceAdded") |

033b73e2 MA |

1615 | `dbus-register-signal' returns an object, which can be used in | |

1890 | ||
1891 | In the first case, the key in the hash table is the list (BUS | |
1892 | INTERFACE MEMBER). BUS is either the symbol `:system' or the symbol | |
1893 | `:session'. INTERFACE is a string which denotes a D-Bus interface, | |
1894 | and MEMBER, also a string, is either a method or a signal INTERFACE is | |
1895 | offering. All arguments but BUS must not be nil. | |
a31d47c7 | 1896 | |

1897 | The value in the hash table is a list of quadruple lists |
1898 | \((UNAME SERVICE PATH HANDLER) (UNAME SERVICE PATH HANDLER) ...). | |
a31d47c7 MA |
1899 | SERVICE is the service name as registered, UNAME is the corresponding |
1900 | unique name. PATH is the object path of the sending object. All of | |
f5306ca3 MA |
1901 | them can be nil, which means a wildcard then. HANDLER is the function |
1902 | to be called when a D-Bus message, which matches the key criteria, | |
13ecc6dc MA |
1903 | arrives. |
1904 | ||
1905 | In the second case, the key in the hash table is the list (BUS SERIAL). | |
1906 | BUS is either the symbol `:system' or the symbol `:session'. SERIAL | |
1907 | is the serial number of the non-blocking method call, a reply is | |
1908 | expected. Both arguments must not be nil. The value in the hash | |
