NAME

     sctp_generic_sendmsg sctp_generic_sendmsg_iov -- send data to a peer

LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <sys/types.h>
     #include <sys/socket.h>
     #include <netinet/sctp.h>

     int
     sctp_generic_sendmsg(int s, void *msg, int msglen, struct sockaddr *to,
         socklen_t len, struct sctp_sndrcvinfo *sinfo, int flags);

     int
     sctp_generic_sendmsg_iov(int s, struct iovec *iov, int iovlen,
         struct sockaddr *to, struct sctp_sndrcvinfo *sinfo, int flags);

DESCRIPTION

     sctp_generic_sendmsg() and sctp_generic_sendmsg_iov() are the true system
     calls used by the sctp_sendmsg(3) and sctp_send(3) 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 usage please see either the sctp_send(3) or
     sctp_sendmsg(3) function calls.

RETURN VALUES

     The call returns the number of bytes written on success and -1 upon
     failure.

ERRORS

     [EBADF]            The argument s is not a valid descriptor.

     [ENOTSOCK]         The argument s is not a socket.
