Function Documentation

int easydbus_add_struct_on_container_msg ( DBusMessage *  msg,
DBusMessageIter *  iter,
struct EasyDbus_elem *  elem 
)

Add struct element to a container element of DBusMessage.

This function it is used for example where there is array of struct, and so iter is a iter connect to open array dbus element.

For internal use only.

Parameters:
msg DBusMessage message.
iter DBusMessageIter iterator from a high level marshal data container.
elem element object that contains struct container.
Returns:
-1 error

0 ok
