1110 | connection used in the same Emacs process, like the one established by | |
1111 | GTK+. It should be used with care for at least the `:system' and | |

1797 | There are two different uses of the hash table: for accessing |
1798 | registered interfaces properties, targeted by signals or method calls, | |
1799 | and for calling handlers in case of non-blocking method call returns. | |
13ecc6dc | 1800 | |
dcbf5805 MA |
1801 | In the first case, the key in the hash table is the list (TYPE BUS |
1802 | INTERFACE MEMBER). TYPE is one of the Lisp symbols `:method', | |
1803 | `:signal' or `:property'. BUS is either a Lisp symbol, `:system' or | |
0c372655 MA |
1804 | `:session', or a string denoting the bus address. INTERFACE is a |
1805 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
1806 | either a method, a signal or a property INTERFACE is offering. All | |
1807 | arguments but BUS must not be nil. | |
a31d47c7 | 1808 | |
dcbf5805 MA |
1809 | The value in the hash table is a list of quadruple lists \((UNAME |
1810 | SERVICE PATH OBJECT [RULE]) ...). SERVICE is the service name as | |
1811 | registered, UNAME is the corresponding unique name. In case of | |
1812 | registered methods and properties, UNAME is nil. PATH is the object | |
1813 | path of the sending object. All of them can be nil, which means a | |
1814 | wildcard then. OBJECT is either the handler to be called when a D-Bus | |
1815 | message, which matches the key criteria, arrives (TYPE `:method' and | |
1816 | `:signal'), or a cons cell containing the value of the property (TYPE | |
1817 | `:property'). | |
13ecc6dc | 1818 | |
dcbf5805 MA |
1819 | For entries of type `:signal', there is also a fifth element RULE, |
1820 | which keeps the match string the signal is registered with. | |
a3de0cbd | 1821 | |
dcbf5805 | 1822 | In the second case, the key in the hash table is the list (:serial BUS |
0c372655 MA |
1823 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a |
1824 | string denoting the bus address. SERIAL is the serial number of the | |
1825 | non-blocking method call, a reply is expected. Both arguments must | |
1826 | not be nil. The value in the hash table is HANDLER, the function to | |
1827 | be called when the D-Bus reply message arrives. */); | |
