SD_BUS_MESSAGE_AT_END(3) sd_bus_message_at_end SD_BUS_MESSAGE_AT_END(3)
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.
NOTES
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.
