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.
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.
