1221 | BUS is either a Lisp symbol, `:system' or `:session', or a string |
1222 | denoting the bus address. | |
13ecc6dc MA |
1223 | |
1224 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |
1225 | object path SERVICE is registered at. INTERFACE is an interface | |
1226 | offered by SERVICE. It must provide METHOD. | |
1227 | ||
1228 | HANDLER is a Lisp function, which is called when the corresponding | |
ca4f31ea MA |
1229 | return message has arrived. If HANDLER is nil, no return message will |
1230 | be expected. | |
13ecc6dc MA |
1231 | |
1232 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
f04bb9b2 | 1233 | specifies the maximum number of milliseconds the method call must |
1574224c | 1234 | return. The default value is 25,000. If the method call doesn't |
13ecc6dc MA |
1235 | return in time, a D-Bus error is raised. |
1236 | ||
1237 | All other arguments ARGS are passed to METHOD as arguments. They are | |
1238 | converted into D-Bus types via the following rules: | |
1239 | ||
1240 | t and nil => DBUS_TYPE_BOOLEAN | |
1241 | number => DBUS_TYPE_UINT32 | |
1242 | integer => DBUS_TYPE_INT32 | |
1243 | float => DBUS_TYPE_DOUBLE | |
1244 | string => DBUS_TYPE_STRING | |
1245 | list => DBUS_TYPE_ARRAY | |
1246 | ||
1247 | All arguments can be preceded by a type symbol. For details about | |
1248 | type symbols, see Info node `(dbus)Type Conversion'. | |
1249 | ||
ca4f31ea | 1250 | Unless HANDLER is nil, the function returns a key into the hash table |
f04bb9b2 MA |
1251 | `dbus-registered-objects-table'. The corresponding entry in the hash |
1252 | table is removed, when the return message has been arrived, and | |
13ecc6dc MA |
1253 | HANDLER is called. |
1254 | ||
1255 | Example: | |

1568 | BUS is either a Lisp symbol, `:system' or `:session', or a string |

033b73e2 MA |
1570 | |

1572 | D-Bus object path SERVICE is registered at. INTERFACE is an interface | |
1573 | offered by SERVICE. It must provide signal SIGNAL. | |
1574 | ||
1575 | All other arguments ARGS are passed to SIGNAL as arguments. They are | |
1576 | converted into D-Bus types via the following rules: | |
1577 | ||
1578 | t and nil => DBUS_TYPE_BOOLEAN | |
1579 | number => DBUS_TYPE_UINT32 | |
1580 | integer => DBUS_TYPE_INT32 | |

1881 | doc: /* Register known name SERVICE on the D-Bus BUS. | |
1882 | ||
1883 | BUS is either a Lisp symbol, `:system' or `:session', or a string | |
1884 | denoting the bus address. | |
1885 | ||
1886 | SERVICE is the D-Bus service name that should be registered. It must | |
1887 | be a known name. | |
1888 | ||
1889 | FLAGS are keywords, which control how the service name is registered. | |
1890 | The following keywords are recognized: | |
1891 | ||
1892 | `:allow-replacement': Allow another service to become the primary | |
1893 | owner if requested. | |
1894 | ||
1895 | `:replace-existing': Request to replace the current primary owner. | |
1896 | ||
1897 | `:do-not-queue': If we can not become the primary owner do not place | |
1898 | us in the queue. | |
1899 | ||
1900 | The function returns a keyword, indicating the result of the | |
1901 | operation. One of the following keywords is returned: | |
1902 | ||
1903 | `:primary-owner': Service has become the primary owner of the | |
1904 | requested name. | |
1905 | ||
1906 | `:in-queue': Service could not become the primary owner and has been | |
1907 | placed in the queue. | |
1908 | ||
1909 | `:exists': Service is already in the queue. | |
1910 | ||
1911 | `:already-owner': Service is already the primary owner. | |
1912 | ||
1913 | Example: | |
1914 | ||
1915 | \(dbus-register-service :session dbus-service-emacs) | |
1916 | ||

1993 | SERVICE is the D-Bus service name used by the sending D-Bus object. |
1994 | It can be either a known name or the unique name of the D-Bus object | |
1995 | sending the signal. When SERVICE is nil, related signals from all | |
1996 | D-Bus objects shall be accepted. | |
033b73e2 | 1997 | |

2001 | INTERFACE is an interface offered by SERVICE. It must provide SIGNAL. |

944cc4a8 MA |
2003 | It must accept as arguments the values SIGNAL is sending. |
2004 | ||
2005 | All other arguments ARGS, if specified, must be strings. They stand | |

2275 | There are two different uses of the hash table: for accessing |
2276 | registered interfaces properties, targeted by signals or method calls, | |
2277 | and for calling handlers in case of non-blocking method call returns. | |

2278 | |
2279 | In the first case, the key in the hash table is the list (BUS | |
0c372655 MA |
2280 | INTERFACE MEMBER). BUS is either a Lisp symbol, `:system' or |
2281 | `:session', or a string denoting the bus address. INTERFACE is a | |
2282 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
2283 | either a method, a signal or a property INTERFACE is offering. All | |
2284 | arguments but BUS must not be nil. | |
a31d47c7 | 2285 | |
f5306ca3 | 2286 | The value in the hash table is a list of quadruple lists |
f04bb9b2 | 2287 | \((UNAME SERVICE PATH OBJECT) (UNAME SERVICE PATH OBJECT) ...). |
a31d47c7 | 2288 | SERVICE is the service name as registered, UNAME is the corresponding |
f04bb9b2 MA |
2289 | unique name. In case of registered methods and properties, UNAME is |
2290 | nil. PATH is the object path of the sending object. All of them can | |
2291 | be nil, which means a wildcard then. OBJECT is either the handler to | |
2292 | be called when a D-Bus message, which matches the key criteria, | |
2293 | arrives (methods and signals), or a cons cell containing the value of | |
2294 | the property. | |
13ecc6dc | 2295 | |
0c372655 MA |
2296 | In the second case, the key in the hash table is the list (BUS |
2297 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a | |
2298 | string denoting the bus address. SERIAL is the serial number of the | |
2299 | non-blocking method call, a reply is expected. Both arguments must | |
2300 | not be nil. The value in the hash table is HANDLER, the function to | |
2301 | be called when the D-Bus reply message arrives. */); | |
