Looks like it.

sockstat | grep tcp
murray   sshd       80460 3  tcp4   192.168.1.23:22       192.168.1.2:48594
root     sshd       80457 3  tcp4   192.168.1.23:22       192.168.1.2:48594
ntpd     ntpd       67212 6  tcp4   *:4460                *:*
ntpd     ntpd       67212 7  tcp6   *:4460                *:*
root     sshd       755   3  tcp6   *:22                  *:*
root     sshd       755   4  tcp4   *:22                  *:*
root     sendmail   723   4  tcp4   127.0.0.1:25          *:*

Header (that grep drops):
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS      

There is no gpsd on that system so the lack of 2947 is expected.  I assume the 
4460 is a good example.

On FreeBSD, -p is for protocol.

>From the man page:

     -f address_family, -p protocol
           Limit display to those records of the specified address_family or a
           single protocol.  The following address families and protocols are
           recognized:

           Family                               Protocols
           inet (AF_INET)                       divert, icmp, igmp, ip, ipsec,
                                                pim, sctp, tcp, udp
           inet6 (AF_INET6)                     icmp6, ip6, ipsec6, rip6,
                                                sctp, tcp, udp
           pfkey (PF_KEY)                       pfkey
           netgraph, ng (AF_NETGRAPH)           ctrl, data
           unix (AF_UNIX)
           link (AF_LINK)

           The program will complain if protocol is unknown or if there is no
           statistics routine for it.
