Expand description

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 descriptor
  • data: Struct that implements IntoIterator with SendMmsgData items
  • flags: Optional flags passed directly to the operating system.

§Returns

Vec with numbers of sent bytes on each sent message.
