1110 | is linked with the gtk toolkit, and it runs in a GTK-aware environment | |

1112 | ||
1113 | When PRIVATE is non-nil, a new connection is established instead of | |
1114 | reusing an existing one. It results in a new unique name at the bus. | |
1115 | This can be used, if it is necessary to distinguish from another | |
1116 | connection used in the same Emacs process, like the one established by | |
1117 | GTK+. It should be used with care for at least the `:system' and | |

f04bb9b2 MA |
1814 | There are two different uses of the hash table: for accessing |
1815 | registered interfaces properties, targeted by signals or method calls, | |
1816 | and for calling handlers in case of non-blocking method call returns. | |
13ecc6dc | 1817 | |
dcbf5805 MA |
1818 | In the first case, the key in the hash table is the list (TYPE BUS |
1819 | INTERFACE MEMBER). TYPE is one of the Lisp symbols `:method', | |
1820 | `:signal' or `:property'. BUS is either a Lisp symbol, `:system' or | |
0c372655 MA |
1821 | `:session', or a string denoting the bus address. INTERFACE is a |
1822 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
1823 | either a method, a signal or a property INTERFACE is offering. All | |
1824 | arguments but BUS must not be nil. | |
a31d47c7 | 1825 | |
dcbf5805 MA |
1826 | The value in the hash table is a list of quadruple lists \((UNAME |
1827 | SERVICE PATH OBJECT [RULE]) ...). SERVICE is the service name as | |
1828 | registered, UNAME is the corresponding unique name. In case of | |
1829 | registered methods and properties, UNAME is nil. PATH is the object | |
1830 | path of the sending object. All of them can be nil, which means a | |
1831 | wildcard then. OBJECT is either the handler to be called when a D-Bus | |
1832 | message, which matches the key criteria, arrives (TYPE `:method' and | |
1833 | `:signal'), or a cons cell containing the value of the property (TYPE | |
1834 | `:property'). | |
13ecc6dc | 1835 | |
dcbf5805 MA |
1836 | For entries of type `:signal', there is also a fifth element RULE, |
1837 | which keeps the match string the signal is registered with. | |
a3de0cbd | 1838 | |
dcbf5805 | 1839 | In the second case, the key in the hash table is the list (:serial BUS |
0c372655 MA |
1840 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a |
1841 | string denoting the bus address. SERIAL is the serial number of the | |
1842 | non-blocking method call, a reply is expected. Both arguments must | |
1843 | not be nil. The value in the hash table is HANDLER, the function to | |
1844 | be called when the D-Bus reply message arrives. */); | |
