man 7 unix is promising:
ANCILLARY MESSAGES
For historical reasons these ancillary message type are
specified with a SOL_SOCKET type even though they are
PF_UNIX specific. To send them set the cmsg_level field
of the struct cmsghdr to SOL_SOCKET and the cmsg_type
field to the type. For more information see cmsg(3).
SCM_RIGHTS
Send or receive a set of open file descriptors from
another process. The data portion contains a inte
ger array of the file descriptors. The passed file
descriptors behave as like they have been created
with dup(2).
thanks, all!
