51.Sh DESCRIPTION
52.Fn sctp_generic_sendmsg
53and
54.Fn sctp_generic_sendmsg_iov
55are the true system calls used by the
56.Xr sctp_sendmsg 3
57and
58.Xr sctp_send 3
59function calls.
60These are more efficient since they are
61true system calls but they are specific to
62.Fx
63and can be expected
64.Em not
65to be present on any other operating
66system.
67For detailed usage please see either the
68.Xr sctp_send 3
69or
70.Xr sctp_sendmsg 3
71function calls.
72.Sh RETURN VALUES
73The call returns the number of bytes written on success and -1 upon failure.
