int sd_bus_message_at_end(sd_bus_message *m, int complete);
Описание (Description)
sd_bus_message_at_end() returns whether all data from the
currently opened container in m or all data from all containers
in m has been read. If complete is zero, this function returns
whether all data from the currently opened container has been
read. If complete is non-zero, this function returns whether all
data from all containers in m has been read.

(depending on the value of complete) has been read,
sd_bus_message_at_end() returns a positive integer. If there is
still data left to be read, it returns zero. On failure, it
returns a negative errno-style error code.
