typedef struct { GCallback function; GClosureMarshal marshaller; int data_offset; } DBusGMethodInfo;
Object typically generated by dbus-binding-tool that stores a mapping from introspection data to a function pointer for a C method to be invoked.
GCallback |
C method to invoke |
GClosureMarshal |
Marshaller to invoke method |
int |
Offset into the introspection data |
gchar* dbus_g_method_get_sender (DBusGMethodInvocation *context);
Get the sender of a message so we can send a "reply" later (i.e. send a message directly to a service which invoked the method at a later time).
|
the method context |
Returns : |
the unique name of the sender. It is up to the caller to free the returned string. |
DBusMessage* dbus_g_method_get_reply (DBusGMethodInvocation *context);
Get the reply message to append reply values Used as a sidedoor when you can't generate dbus values of the correct type due to glib binding limitations
|
the method context |
Returns : |
a DBusMessage with the reply |
void dbus_g_method_send_reply (DBusGMethodInvocation *context, DBusMessage *reply);
Used as a sidedoor when you can't generate dbus values of the correct type due to glib binding limitations
|
the method context |
|
the reply message, will be unreffed |
void dbus_g_method_return (DBusGMethodInvocation *context, ...);
Send a return message for a given method invocation, with arguments. This function also frees the sending context.

|
void dbus_g_method_return_error (DBusGMethodInvocation *context, GError *error);
Send a error message for a given method invocation. This function also frees the sending context.
|
