Module shadow_rs::host::syscall::io

Structs

• IoVec
  Analogous to libc::iovec.
• IoVecReader
  A reader which reads data from IoVec buffers of plugin memory.
• IoVecWriter
  A writer which writes data to IoVec buffers of plugin memory.
• MsgHdr
  Analogous to libc::msghdr.

Functions

• read_cstring_vec
  Read an array of strings, each of which with max length linux_api::limits::ARG_MAX. e.g. suitable for execve’s argument and environment string lists.
• read_iovecs
  Read a plugin’s array of libc::iovec into a Vec<IoVec>.
• read_msghdr
  Read a plugin’s libc::msghdr into a MsgHdr.
• read_sockaddr
• update_msghdr
  Used to update a libc::msghdr. Only writes the libc::msghdr msg_namelen, msg_controllen, and msg_flags fields, which are the only fields that can be changed by recvmsg().
• write_partial
  Writes val to val_ptr, but will only write a partial value if val_len_bytes is smaller than the size of val. Returns the number of bytes written.
• write_sockaddr
  Writes the socket address into a buffer at plugin_addr with length plugin_addr_len.
• write_sockaddr_and_len
  Writes the socket address into a buffer at plugin_addr with length plugin_addr_len, and writes the socket address length into plugin_addr_len.
