Here is the caller graph for this function:

sendmmsg()

int sendmmsg	(	int	sockfd,
		struct mmsghdr *	msgvec,
		unsigned int	vlen,
		int	flags
	)

Emulates the real sendmmsg in userland.

The idea behind the proper sendmmsg in FreeBSD and Linux is that multiple datagram messages can be sent using a single system call.

This function doesn't achieve that, but it does reduce ifdefs elsewhere and means we can batch encoding/sending operations.

Parameters

[in]	sockfd	to write packets to.
[in]	msgvec	a pointer to an array of mmsghdr structures. The size of this array is specified in vlen.
[in]	vlen	Length of msgvec.
[in]	flags	same as for sendmsg(2).

Returns

• >= 0 The number of messages sent. Check against vlen to determine if overall operation was successful.
• < 0 on error. Only returned if first operation errors.
