NAME
sd_bus_message_at_end - Check if a message has been fully read
SYNOPSIS
#include <systemd/sd-bus.h>
int sd_bus_message_at_end(sd_bus_message **/m/, int complete);*
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.
RETURN VALUE
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.
Errors
Returned errors may indicate the following problems:
-EINVAL
The m parameter is NULL.
-EPERM
The message is not sealed.
