sd_machine_get_class, sd_machine_get_ifindices — Determine the class and network interface indices of a locally running virtual machine or container.
#include <systemd/sd-login.h>
int sd_machine_get_class( | const char* machine, |
char *class); |
int sd_machine_get_ifindices( | const char* machine, |
int **ifindices); |
sd_machine_get_class() may be used to
determine the class of a locally running virtual machine or
container that is registered with
systemd-machined.service(8).
The string returned is either "vm" or
"container". The returned string needs to be
freed with the libc free(3)
call after use.
sd_machine_get_ifindices() may be used
to determine the numeric indices of the network interfaces on the
host that are pointing towards the specified locally running
virtual machine or container that is registered with
systemd-machined.service(8).
The returned array needs to be freed with the libc free(3)
call after use.
On success, these calls return 0 or a positive integer. On failure, these calls return a negative errno-style error code.
The sd_machine_get_class() and
sd_machine_get_ifindices() interfaces are
available as a shared library, which can be compiled and linked to
with the
libsystemd pkg-config(1)
file.
