§sock_recv_from()

Receive a message and its peer address from a socket. Note: This is similar to recvfrom in POSIX, though it also supports reading the data into multiple buffers in the manner of readv.

§Parameters

  • ri_data - List of scatter/gather vectors to which to store data.
  • ri_flags - Message flags.

§Return

Number of bytes stored in ri_data and message flags.
