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.
