+.SH "NAME"
+sd_machine_get_class, sd_machine_get_ifindices \- Determine the class and network interface indices of a locally running virtual machine or container
+.SH "SYNOPSIS"

+.BI "int sd_machine_get_class(const\ char*\ " "machine" ", char\ **" "class" ");"

+.BI "int sd_machine_get_ifindices(const\ char*\ " "machine" ", int\ **" "ret_ifindices" ");"
+.SH "DESCRIPTION"
+.PP
+\fBsd_machine_get_class()\fR
+may be used to determine the class of a locally running virtual machine or container that is registered with
+\fBsystemd-machined.service\fR(8)\&. The string returned is either
+"vm"
+or
+"container"\&. The returned string needs to be freed with the libc
+\fBfree\fR(3)
+call after use\&.
+.PP
+\fBsd_machine_get_ifindices()\fR
+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\&. The vm or container must be registered with
+\fBsystemd-machined.service\fR(8)\&. The output parameter
+\fIret_ifindices\fR
+may be passed as
+\fBNULL\fR
+when the output value is not needed\&. The returned array needs to be freed with the libc
+\fBfree\fR(3)
+call after use\&.
+.SH "RETURN VALUE"
+.PP
+On success, these functions return a non\-negative integer\&.
+\fBsd_machine_get_ifindices()\fR
+returns the number of the relevant network interfaces\&. On failure, these calls return a negative errno\-style error code\&.
+.SS "Errors"
+.PP
+Returned errors may indicate the following problems:
+.PP
+\fB\-ENXIO\fR
+.RS 4
+The specified machine does not exist or is currently not running\&.
+.RE
+.PP
+\fB\-EINVAL\fR
+.RS 4
+An input parameter was invalid (out of range, or
+\fBNULL\fR, where that is not accepted)\&.
+.RE
+.PP
+\fB\-ENOMEM\fR
+.RS 4
+Memory allocation failed\&.
+.RE
+.SH "NOTES"
+.PP
+Functions described here are available as a shared library, which can be compiled against and linked to with the
+\fBlibsystemd\fR\ \&\fBpkg-config\fR(1)
+file\&.
+.PP
+The code described here uses
+\fBgetenv\fR(3), which is declared to be not multi\-thread\-safe\&. This means that the code calling the functions described here must not call
+\fBsetenv\fR(3)
+from a parallel thread\&. It is recommended to only do calls to
+\fBsetenv()\fR
+from an early phase of the program when no other threads have been started\&.
+.SH "HISTORY"
+.PP
+\fBsd_machine_get_class()\fR
+and
+\fBsd_machine_get_ifindices()\fR
+were added in version 217\&.
