sd_bus_message_at_end — Check if a message has been fully read
#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.
Functions described here are available as a shared
library, which can be compiled against and linked to with the
libsystemd pkg-config(1)
file.
All functions listed here are thread-agnostic and only a single thread may operate on a given object at any given time. Different threads may access the same object at different times. Multiple independent objects may be used from different threads in parallel.
The code described here uses
getenv(3),
which is declared to be not multi-thread-safe. This means that the code calling the functions described
here must not call
setenv(3)
from a parallel thread. It is recommended to only do calls to setenv()
from an early phase of the program when no other threads have been started.
