Operation codes that can be used to construct squeue::Entrys.
Structs
Accept a new connection on a socket, equivalent to
accept4(2).Attempt to cancel an already issued request.
Close a file descriptor, equivalent to
close(2).Connect a socket, equivalent to
connect(2).Modify an epoll file descriptor, equivalent to
epoll_ctl(2).Predeclare an access pattern for file data, equivalent to
posix_fadvise(2).FallocateDeprecated
Preallocate or deallocate space to a file, equivalent to
fallocate(2).Preallocate or deallocate space to a file, equivalent to
fallocate(2).This command is an alternative to using
Submitter::register_files_update which then
works in an async fashion, like the rest of the io_uring commands.File sync, equivalent to
fsync(2).Create a hard link, equivalent to
linkat2(2).This request must be linked with another request through
Flags::IO_LINK which is described below.
Unlike Timeout, LinkTimeout acts on the linked request, not the completion queue.Give advice about use of memory, equivalent to
madvise(2).Make a directory, equivalent to
mkdirat2(2).Do not perform any I/O.
Open a file, equivalent to
openat(2).Open a file, equivalent to
openat2(2).Poll the specified fd.
Remove an existing poll request.
Register
nbufs buffers that each have the length len with ids starting from big in the
group bgid that can be used for any request. See
BUFFER_SELECT for more info.Issue the equivalent of a
pread(2) or pwrite(2) system callRead from pre-mapped buffers that have been previously registered with
Submitter::register_buffers.Vectored read, equivalent to
preadv2(2).Receive a message from a socket, equivalent to
recv(2).Receive a message on a socket, equivalent to
recvmsg(2).Remove some number of buffers from a buffer group. See
BUFFER_SELECT for more info.Send a message on a socket, equivalent to
send(2).Send a message on a socket, equivalent to
send(2).Send a zerocopy message on a socket, equivalent to
send(2).Splice data to/from a pipe, equivalent to
splice(2).Get file status, equivalent to
statx(2).Create a symlink, equivalent to
symlinkat2(2).Sync a file segment with disk, equivalent to
sync_file_range(2).Duplicate pipe content, equivalent to
tee(2).Register a timeout operation.
Attempt to remove an existing timeout operation.
A file/device-specific 16-byte command, akin (but not equivalent) to
ioctl(2).A file/device-specific 80-byte command, akin (but not equivalent) to
ioctl(2).Issue the equivalent of a
pread(2) or pwrite(2) system callWrite to pre-mapped buffers that have been previously registered with
Submitter::register_buffers.Vectored write, equivalent to
pwritev2(2).
