An extension of sendmsg that allows the caller to transmit multiple
messages on a socket using a single system call. This has performance
benefits for some applications.
Allocations are performed for cmsgs and to build msghdr buffer
Arguments
fd: Socket file descriptordata: Struct that implementsIntoIteratorwithSendMmsgDataitemsflags: Optional flags passed directly to the operating system.
Returns
Vec with numbers of sent bytes on each sent message.
