Module 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.
