NAME

       nbd_supports_vsock - true if libnbd was compiled with support for AF_VSOCK

SYNOPSIS

        #include <libnbd.h>

        int nbd_supports_vsock (
              struct nbd_handle *h
            );

DESCRIPTION

       Returns true if libnbd was compiled with support for the "AF_VSOCK" family of sockets, or
       false if not.

       Note that on the Linux operating system, this returns true if there is compile-time
       support, but you may still need runtime support for some aspects of AF_VSOCK usage; for
       example, use of "VMADDR_CID_LOCAL" as the server name requires that the vsock_loopback
       kernel module is loaded.

RETURN VALUE

       This call returns a boolean value.

ERRORS

       This function does not fail.

       The following parameters must not be NULL: "h".  For more information see "Non-NULL
       parameters" in libnbd(3).

VERSION

       This function first appeared in libnbd 1.16.

       If you need to test if this function is available at compile time check if the following
       macro is defined:

        #define LIBNBD_HAVE_NBD_SUPPORTS_VSOCK 1
