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.
