NAME

6       sd_bus_message_at_end - Check if a message has been fully read
7

SYNOPSIS

9       #include <systemd/sd-bus.h>
10
11       int sd_bus_message_at_end(sd_bus_message *m, int complete);
12

DESCRIPTION

14       sd_bus_message_at_end() returns whether all data from the currently
15       opened container in m or all data from all containers in m has been
16       read. If complete is zero, this function returns whether all data from
17       the currently opened container has been read. If complete is non-zero,
18       this function returns whether all data from all containers in m has
19       been read.
20

RETURN VALUE

22       If all data from all containers or the current container (depending on
23       the value of complete) has been read, sd_bus_message_at_end() returns a
24       positive integer. If there is still data left to be read, it returns
25       zero. On failure, it returns a negative errno-style error code.
26
27   Errors
28       Returned errors may indicate the following problems:
29
30       -EINVAL
31           The m parameter is NULL.
32
33       -EPERM
34           The message is not sealed.
35

NOTES

37       Functions described here are available as a shared library, which can
38       be compiled against and linked to with the libsystemd pkg-config(1)
39       file.
40
41       The code described here uses getenv(3), which is declared to be not
42       multi-thread-safe. This means that the code calling the functions
43       described here must not call setenv(3) from a parallel thread. It is
44       recommended to only do calls to setenv() from an early phase of the
45       program when no other threads have been started.
