1054 | connection used in the same Emacs process, like the one established by | |
1055 | GTK+. It should be used with care for at least the `:system' and | |

f04bb9b2 MA |
1740 | There are two different uses of the hash table: for accessing |
1741 | registered interfaces properties, targeted by signals or method calls, | |
1742 | and for calling handlers in case of non-blocking method call returns. | |
13ecc6dc | 1743 | |
dcbf5805 MA |
1744 | In the first case, the key in the hash table is the list (TYPE BUS |
1745 | INTERFACE MEMBER). TYPE is one of the Lisp symbols `:method', | |
1746 | `:signal' or `:property'. BUS is either a Lisp symbol, `:system' or | |
0c372655 MA |
1747 | `:session', or a string denoting the bus address. INTERFACE is a |
1748 | string which denotes a D-Bus interface, and MEMBER, also a string, is | |
1749 | either a method, a signal or a property INTERFACE is offering. All | |
1750 | arguments but BUS must not be nil. | |
a31d47c7 | 1751 | |
dcbf5805 MA |
1752 | The value in the hash table is a list of quadruple lists \((UNAME |
1753 | SERVICE PATH OBJECT [RULE]) ...). SERVICE is the service name as | |
1754 | registered, UNAME is the corresponding unique name. In case of | |
1755 | registered methods and properties, UNAME is nil. PATH is the object | |
1756 | path of the sending object. All of them can be nil, which means a | |
1757 | wildcard then. OBJECT is either the handler to be called when a D-Bus | |
1758 | message, which matches the key criteria, arrives (TYPE `:method' and | |
1759 | `:signal'), or a cons cell containing the value of the property (TYPE | |
1760 | `:property'). | |
13ecc6dc | 1761 | |
dcbf5805 MA |
1762 | For entries of type `:signal', there is also a fifth element RULE, |
1763 | which keeps the match string the signal is registered with. | |
a3de0cbd | 1764 | |
dcbf5805 | 1765 | In the second case, the key in the hash table is the list (:serial BUS |
0c372655 MA |
1766 | SERIAL). BUS is either a Lisp symbol, `:system' or `:session', or a |
1767 | string denoting the bus address. SERIAL is the serial number of the | |
1768 | non-blocking method call, a reply is expected. Both arguments must | |
1769 | not be nil. The value in the hash table is HANDLER, the function to | |
1770 | be called when the D-Bus reply message arrives. */); | |
