# [NAME](#NAME)

sctp\_send - Send a message from a SCTP socket.

# [SYNOPSIS](#SYNOPSIS)

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

int sctp_send(int sd, const void * msg, size_t len,
                 const struct sctp_sndrcvinfo *sinfo,
                 uint32_t flags);
```

# [DESCRIPTION](#DESCRIPTION)

**sctp\_send** is a wrapper library function that can be used to send a message from a socket without the use of the CMSG header structures. *sd* is the socket descriptor from which the message pointed to by *msg* of length *len* is sent. *sinfo* is a pointer to a sctp\_sndrcvinfo structure. *flags* parameter is composed of a bitwise OR of the flags that can be be passed as the 3rd argument of a standard sendmsg() call.

# [RETURN VALUE](#RETURN_VALUE)

On success, **sctp\_sendmsg** returns the number of bytes sent or -1 if an error occurred.
