928 | ||
929 | BUS is either the symbol `:system' or the symbol `:session'. | |
930 | ||
931 | SERVICE is the D-Bus service name to be used. PATH is the D-Bus | |
932 | object path SERVICE is registered at. INTERFACE is an interface | |
933 | offered by SERVICE. It must provide METHOD. | |
934 | ||
935 | HANDLER is a Lisp function, which is called when the corresponding | |
936 | return message has arrived. | |
937 | ||
938 | If the parameter `:timeout' is given, the following integer TIMEOUT | |
939 | specifies the maximun number of milliseconds the method call must | |
940 | return. The default value is 25.000. If the method call doesn't | |
941 | return in time, a D-Bus error is raised. | |
942 | ||
943 | All other arguments ARGS are passed to METHOD as arguments. They are | |
944 | converted into D-Bus types via the following rules: | |
945 | ||
946 | t and nil => DBUS_TYPE_BOOLEAN | |
947 | number => DBUS_TYPE_UINT32 | |
948 | integer => DBUS_TYPE_INT32 | |
949 | float => DBUS_TYPE_DOUBLE | |
950 | string => DBUS_TYPE_STRING | |
951 | list => DBUS_TYPE_ARRAY | |
952 | ||
953 | All arguments can be preceded by a type symbol. For details about | |
954 | type symbols, see Info node `(dbus)Type Conversion'. | |
955 | ||
956 | The function returns a key into the hash table | |
957 | `dbus-registered-functions-table'. The corresponding entry in the | |
958 | hash table is removed, when the return message has been arrived, and | |
959 | HANDLER is called. | |

1875 | There are two different uses of the hash table: for calling registered |
1876 | functions, targeted by signals or method calls, and for calling | |
1877 | handlers in case of non-blocking method call returns. | |
1878 | ||
1879 | In the first case, the key in the hash table is the list (BUS | |
1880 | INTERFACE MEMBER). BUS is either the symbol `:system' or the symbol | |
1881 | `:session'. INTERFACE is a string which denotes a D-Bus interface, | |
1882 | and MEMBER, also a string, is either a method or a signal INTERFACE is | |
1883 | offering. All arguments but BUS must not be nil. | |
a31d47c7 | 1884 | |
f5306ca3 MA |
1885 | The value in the hash table is a list of quadruple lists |
1886 | \((UNAME SERVICE PATH HANDLER) (UNAME SERVICE PATH HANDLER) ...). | |
a31d47c7 MA |
1887 | SERVICE is the service name as registered, UNAME is the corresponding |
1888 | unique name. PATH is the object path of the sending object. All of | |
f5306ca3 MA |
1889 | them can be nil, which means a wildcard then. HANDLER is the function |
1890 | to be called when a D-Bus message, which matches the key criteria, | |
13ecc6dc MA |
1891 | arrives. |
1892 | ||
1893 | In the second case, the key in the hash table is the list (BUS SERIAL). | |
1894 | BUS is either the symbol `:system' or the symbol `:session'. SERIAL | |
1895 | is the serial number of the non-blocking method call, a reply is | |
1896 | expected. Both arguments must not be nil. The value in the hash | |
