Expand description

Receive message in scatter-gather vectors from a socket, and optionally receive ancillary data into the provided buffer. If no ancillary data is desired, use () as the type parameter.

§Arguments

  • fd: Socket file descriptor
  • iov: Scatter-gather list of buffers to receive the message
  • cmsg_buffer: Space to receive ancillary data. Should be created by cmsg_space!
  • flags: Optional flags passed directly to the operating system.
