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 .

Added in version 246.

-EPERM

The message is not sealed.

Added in version 246.

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.

HISTORY

sd_bus_message_at_end() was added in version 246.
