1193 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |

1195 | offered by SERVICE. It must provide METHOD. | |
1196 | ||
1197 | HANDLER is a Lisp function, which is called when the corresponding | |
ca4f31ea MA |
1198 | return message has arrived. If HANDLER is nil, no return message will |
1199 | be expected. | |
13ecc6dc MA |
1200 | |
1201 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
f04bb9b2 | 1202 | specifies the maximum number of milliseconds the method call must |
1574224c | 1203 | return. The default value is 25,000. If the method call doesn't |
13ecc6dc MA |
1204 | return in time, a D-Bus error is raised. |
1205 | ||
1206 | All other arguments ARGS are passed to METHOD as arguments. They are | |
1207 | converted into D-Bus types via the following rules: | |
1208 | ||
1209 | t and nil => DBUS_TYPE_BOOLEAN | |
1210 | number => DBUS_TYPE_UINT32 | |
1211 | integer => DBUS_TYPE_INT32 | |
1212 | float => DBUS_TYPE_DOUBLE | |
1213 | string => DBUS_TYPE_STRING | |
1214 | list => DBUS_TYPE_ARRAY | |
1215 | ||
1216 | All arguments can be preceded by a type symbol. For details about | |
1217 | type symbols, see Info node `(dbus)Type Conversion'. | |
1218 | ||
ca4f31ea | 1219 | Unless HANDLER is nil, the function returns a key into the hash table |
f04bb9b2 MA |
1220 | `dbus-registered-objects-table'. The corresponding entry in the hash |
1221 | table is removed, when the return message has been arrived, and | |

1845 | BUS is either a Lisp symbol, `:system' or `:session', or a string | |
1846 | denoting the bus address. | |
1847 | ||
1848 | SERVICE is the D-Bus service name that should be registered. It must | |
1849 | be a known name. | |
1850 | ||
1851 | FLAGS are keywords, which control how the service name is registered. | |
1852 | The following keywords are recognized: | |
1853 | ||
1854 | `:allow-replacement': Allow another service to become the primary | |
1855 | owner if requested. | |
1856 | ||
1857 | `:replace-existing': Request to replace the current primary owner. | |
1858 | ||
1859 | `:do-not-queue': If we can not become the primary owner do not place | |
1860 | us in the queue. | |
1861 | ||
1862 | The function returns a keyword, indicating the result of the | |
1863 | operation. One of the following keywords is returned: | |
1864 | ||
1865 | `:primary-owner': Service has become the primary owner of the | |
1866 | requested name. | |
1867 | ||
1868 | `:in-queue': Service could not become the primary owner and has been | |
1869 | placed in the queue. | |
1870 | ||
1871 | `:exists': Service is already in the queue. | |
1872 | ||
1873 | `:already-owner': Service is already the primary owner. | |

0c372655 MA |
1953 | BUS is either a Lisp symbol, `:system' or `:session', or a string |
1954 | denoting the bus address. | |
033b73e2 | 1955 | |
39abdd4a MA |
1956 | SERVICE is the D-Bus service name used by the sending D-Bus object. |
1957 | It can be either a known name or the unique name of the D-Bus object | |
1958 | sending the signal. When SERVICE is nil, related signals from all | |
1959 | D-Bus objects shall be accepted. | |
033b73e2 | 1960 | |
39abdd4a MA |
1961 | PATH is the D-Bus object path SERVICE is registered. It can also be |
1962 | nil if the path name of incoming signals shall not be checked. | |
033b73e2 | 1963 | |
39abdd4a MA |
1964 | INTERFACE is an interface offered by SERVICE. It must provide SIGNAL. |
1965 | HANDLER is a Lisp function to be called when the signal is received. | |
944cc4a8 MA |
1966 | It must accept as arguments the values SIGNAL is sending. |
1967 | ||
1968 | All other arguments ARGS, if specified, must be strings. They stand | |
1969 | for the respective arguments of the signal in their order, and are | |
1970 | used for filtering as well. A nil argument might be used to preserve | |
1971 | the order. | |
1972 | ||
1973 | INTERFACE, SIGNAL and HANDLER must not be nil. Example: | |
033b73e2 MA |
1974 | |
1975 | \(defun my-signal-handler (device) | |
1976 | (message "Device %s added" device)) | |

2303 | There are two different uses of the hash table: for accessing |
2304 | registered interfaces properties, targeted by signals or method calls, | |
2305 | and for calling handlers in case of non-blocking method call returns. | |
13ecc6dc MA |
2306 | |
2307 | In the first case, the key in the hash table is the list (BUS | |
0c372655 MA |
2308 | INTERFACE MEMBER). BUS is either a Lisp symbol, `:system' or |
2309 | `:session', or a string denoting the bus address. INTERFACE is a | |
2310 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
2311 | either a method, a signal or a property INTERFACE is offering. All | |
2312 | arguments but BUS must not be nil. | |
a31d47c7 | 2313 | |
f5306ca3 | 2314 | The value in the hash table is a list of quadruple lists |
f04bb9b2 | 2315 | \((UNAME SERVICE PATH OBJECT) (UNAME SERVICE PATH OBJECT) ...). |
a31d47c7 | 2316 | SERVICE is the service name as registered, UNAME is the corresponding |
f04bb9b2 MA |
2317 | unique name. In case of registered methods and properties, UNAME is |
2318 | nil. PATH is the object path of the sending object. All of them can | |
2319 | be nil, which means a wildcard then. OBJECT is either the handler to | |
2320 | be called when a D-Bus message, which matches the key criteria, | |
2321 | arrives (methods and signals), or a cons cell containing the value of | |
2322 | the property. | |
13ecc6dc | 2323 | |
0c372655 MA |
2324 | In the second case, the key in the hash table is the list (BUS |
2325 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a | |
2326 | string denoting the bus address. SERIAL is the serial number of the | |
2327 | non-blocking method call, a reply is expected. Both arguments must | |
2328 | not be nil. The value in the hash table is HANDLER, the function to | |
2329 | be called when the D-Bus reply message arrives. */); | |
