962 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |

964 | offered by SERVICE. It must provide METHOD. | |
965 | ||
90b3fc84 | 966 | If the parameter `:timeout' is given, the following integer TIMEOUT |
f04bb9b2 | 967 | specifies the maximum number of milliseconds the method call must |
1574224c | 968 | return. The default value is 25,000. If the method call doesn't |

976 | integer => DBUS_TYPE_INT32 | |

87cf1a39 | 979 | list => DBUS_TYPE_ARRAY |
033b73e2 | 980 | |

981 | All arguments can be preceded by a type symbol. For details about |
982 | type symbols, see Info node `(dbus)Type Conversion'. | |
033b73e2 MA |

1161 | BUS is either a Lisp symbol, `:system' or `:session', or a string |
1162 | denoting the bus address. | |
13ecc6dc MA |
1163 | |
1164 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |
1165 | object path SERVICE is registered at. INTERFACE is an interface | |
1166 | offered by SERVICE. It must provide METHOD. | |
1167 | ||
1168 | HANDLER is a Lisp function, which is called when the corresponding | |
ca4f31ea MA |
1169 | return message has arrived. If HANDLER is nil, no return message will |
1170 | be expected. | |
13ecc6dc MA |
1171 | |
1172 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
f04bb9b2 | 1173 | specifies the maximum number of milliseconds the method call must |
1574224c | 1174 | return. The default value is 25,000. If the method call doesn't |
13ecc6dc MA |
1175 | return in time, a D-Bus error is raised. |
1176 | ||
1177 | All other arguments ARGS are passed to METHOD as arguments. They are | |
1178 | converted into D-Bus types via the following rules: | |
1179 | ||
1180 | t and nil => DBUS_TYPE_BOOLEAN | |
1181 | number => DBUS_TYPE_UINT32 | |
1182 | integer => DBUS_TYPE_INT32 | |
1183 | float => DBUS_TYPE_DOUBLE | |
1184 | string => DBUS_TYPE_STRING | |
1185 | list => DBUS_TYPE_ARRAY | |
1186 | ||
1187 | All arguments can be preceded by a type symbol. For details about | |
1188 | type symbols, see Info node `(dbus)Type Conversion'. | |
1189 | ||
ca4f31ea | 1190 | Unless HANDLER is nil, the function returns a key into the hash table |
f04bb9b2 MA |
1191 | `dbus-registered-objects-table'. The corresponding entry in the hash |
1192 | table is removed, when the return message has been arrived, and | |

1853 | BUS is either a Lisp symbol, `:system' or `:session', or a string |
1854 | denoting the bus address. | |
033b73e2 | 1855 | |
39abdd4a MA |
1856 | SERVICE is the D-Bus service name used by the sending D-Bus object. |
1857 | It can be either a known name or the unique name of the D-Bus object | |
1858 | sending the signal. When SERVICE is nil, related signals from all | |
1859 | D-Bus objects shall be accepted. | |
033b73e2 | 1860 | |
39abdd4a MA |
1861 | PATH is the D-Bus object path SERVICE is registered. It can also be |
1862 | nil if the path name of incoming signals shall not be checked. | |
033b73e2 | 1863 | |
39abdd4a MA |
1864 | INTERFACE is an interface offered by SERVICE. It must provide SIGNAL. |
1865 | HANDLER is a Lisp function to be called when the signal is received. | |
944cc4a8 MA |
1866 | It must accept as arguments the values SIGNAL is sending. |
1867 | ||
1868 | All other arguments ARGS, if specified, must be strings. They stand | |
1869 | for the respective arguments of the signal in their order, and are | |
1870 | used for filtering as well. A nil argument might be used to preserve | |
1871 | the order. | |
1872 | ||
1873 | INTERFACE, SIGNAL and HANDLER must not be nil. Example: | |
033b73e2 MA |
1874 | |
1875 | \(defun my-signal-handler (device) | |
1876 | (message "Device %s added" device)) | |

2172 | There are two different uses of the hash table: for accessing |

2175 | |
2176 | In the first case, the key in the hash table is the list (BUS | |
0c372655 MA |
2177 | INTERFACE MEMBER). BUS is either a Lisp symbol, `:system' or |
2178 | `:session', or a string denoting the bus address. INTERFACE is a | |
2179 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
2180 | either a method, a signal or a property INTERFACE is offering. All | |
2181 | arguments but BUS must not be nil. | |
a31d47c7 | 2182 | |
f5306ca3 | 2183 | The value in the hash table is a list of quadruple lists |
f04bb9b2 | 2184 | \((UNAME SERVICE PATH OBJECT) (UNAME SERVICE PATH OBJECT) ...). |
a31d47c7 | 2185 | SERVICE is the service name as registered, UNAME is the corresponding |
f04bb9b2 MA |
2186 | unique name. In case of registered methods and properties, UNAME is |
2187 | nil. PATH is the object path of the sending object. All of them can | |
2188 | be nil, which means a wildcard then. OBJECT is either the handler to | |
2189 | be called when a D-Bus message, which matches the key criteria, | |
2190 | arrives (methods and signals), or a cons cell containing the value of | |
2191 | the property. | |
13ecc6dc | 2192 | |
0c372655 MA |
2193 | In the second case, the key in the hash table is the list (BUS |
2194 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a | |
2195 | string denoting the bus address. SERIAL is the serial number of the | |
2196 | non-blocking method call, a reply is expected. Both arguments must | |
2197 | not be nil. The value in the hash table is HANDLER, the function to | |
