40.In sys/types.h
41.In sys/socket.h
42.In netinet/sctp.h

47.Sh DESCRIPTION
48.Fn sctp_generic_sendmsg
49and
50.Fn sctp_generic_sendmsg_iov
51are the true system calls used by the
52.Xr sctp_sendmsg 3
53and
54.Xr sctp_send 3
55function calls.
56These are more efficient since they are
57true system calls but they are specific to
58.Fx
59and can be expected
60.Em not
61to be present on any other operating
62system.
63For detailed usage please see either the
64.Xr sctp_send 3
65or
66.Xr sctp_sendmsg 3
67function calls.
68.Sh RETURN VALUES
69The call returns the number of bytes written on success and -1 upon failure.
