sd_bus_message_at_end - Man Page

#include <systemd/sd-bus.h>

int sd_bus_message_at_end(sd_bus_message *m, int complete);

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.

If all data from all containers or the current container (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.

These APIs are implemented as a shared library, which can be compiled and linked to with the libsystemd pkg-config(1) file.
