1193 | ||
1194 | HANDLER is a Lisp function, which is called when the corresponding | |

13ecc6dc MA |
1197 | |
1198 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
f04bb9b2 | 1199 | specifies the maximum number of milliseconds the method call must |
1574224c | 1200 | return. The default value is 25,000. If the method call doesn't |

1205 | ||
1206 | t and nil => DBUS_TYPE_BOOLEAN | |
1207 | number => DBUS_TYPE_UINT32 | |
1208 | integer => DBUS_TYPE_INT32 | |

033b73e2 | 1844 | |
39abdd4a MA |
1845 | SERVICE is the D-Bus service name used by the sending D-Bus object. |
1846 | It can be either a known name or the unique name of the D-Bus object | |
1847 | sending the signal. When SERVICE is nil, related signals from all | |
1848 | D-Bus objects shall be accepted. | |
033b73e2 | 1849 | |
39abdd4a MA |
1850 | PATH is the D-Bus object path SERVICE is registered. It can also be |
1851 | nil if the path name of incoming signals shall not be checked. | |
033b73e2 | 1852 | |
39abdd4a MA |
1853 | INTERFACE is an interface offered by SERVICE. It must provide SIGNAL. |
1854 | HANDLER is a Lisp function to be called when the signal is received. | |
944cc4a8 MA |
1855 | It must accept as arguments the values SIGNAL is sending. |
1856 | ||
1857 | All other arguments ARGS, if specified, must be strings. They stand | |
1858 | for the respective arguments of the signal in their order, and are | |
1859 | used for filtering as well. A nil argument might be used to preserve | |
1860 | the order. | |

1862 | INTERFACE, SIGNAL and HANDLER must not be nil. Example: | |

2170 | In the first case, the key in the hash table is the list (BUS | |
0c372655 MA |
2171 | INTERFACE MEMBER). BUS is either a Lisp symbol, `:system' or |
2172 | `:session', or a string denoting the bus address. INTERFACE is a | |
2173 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
2174 | either a method, a signal or a property INTERFACE is offering. All | |
2175 | arguments but BUS must not be nil. | |

f04bb9b2 MA |
2180 | unique name. In case of registered methods and properties, UNAME is |
2181 | nil. PATH is the object path of the sending object. All of them can | |
2182 | be nil, which means a wildcard then. OBJECT is either the handler to | |
2183 | be called when a D-Bus message, which matches the key criteria, | |
2184 | arrives (methods and signals), or a cons cell containing the value of | |
2185 | the property. | |
13ecc6dc | 2186 | |
0c372655 MA |
2187 | In the second case, the key in the hash table is the list (BUS |
2188 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a | |
2189 | string denoting the bus address. SERIAL is the serial number of the | |
2190 | non-blocking method call, a reply is expected. Both arguments must | |
