+.Sh DESCRIPTION
+The
+.Fn sctp_generic_sendmsg
+and
+.Fn sctp_generic_sendmsg_iov
+are the true system calls used by the
+.Fn sctp_sendmsg
+and 
+.Fn sctp_send
+function calls. These are more efficient since they are
+true system calls but they are specific to FreeBSD and
+can be expected NOT to be present on any other Operating
+System. For detailed useage please see either the
+.Fn sctp_send
+or
+.Fn sctp_sendmsg
+function calls. 
+.Sh RETURN VALUES
+The call returns the number of bytes written on success and -1 upon failure.
+.Sh ERRORS
