Functions

fill

void fill(SubmissionEntry entry, E op)

Uses custom operation definition to fill fields of SubmissionEntry. Can be used in cases, when builtin prep* functions aren't enough.

prepAccept

void prepAccept(SubmissionEntry entry, int fd, ADDR addr, socklen_t addrlen, AcceptFlags flags)

Prepares accept4(2) operation.

prepCancel

void prepCancel(SubmissionEntry entry, D userData)

Prepares operation that cancels existing async work.

prepConnect

void prepConnect(SubmissionEntry entry, int fd, const(ADDR) addr)

Note: Available from Linux 5.5

prepFsync

void prepFsync(SubmissionEntry entry, int fd, FsyncFlags flags)

Prepares fsync operation.

prepLinkTimeout

void prepLinkTimeout(SubmissionEntry entry, KernelTimespec time, TimeoutFlags flags)

Prepares linked timeout operation.

prepNop

void prepNop(SubmissionEntry entry)

Prepares nop operation.

prepPollAdd

void prepPollAdd(SubmissionEntry entry, int fd, PollEvents events)

Poll the fd specified in the submission queue entry for the events specified in the poll_events field. Unlike poll or epoll without EPOLLONESHOT, this interface always works in one shot mode. That is, once the poll operation is completed, it will have to be resubmitted.

prepPollRemove

void prepPollRemove(SubmissionEntry entry, D userData)

Remove an existing poll request. If found, the res field of the CompletionEntry will contain 0. If not found, res will contain -ENOENT.

prepReadFixed

void prepReadFixed(SubmissionEntry entry, int fd, ulong offset, ubyte[] buffer, ushort bufferIndex)

Prepares read_fixed operation.

prepReadv

void prepReadv(SubmissionEntry entry, int fd, V buffer, ulong offset)

Prepares readv operation.

prepRecvMsg

void prepRecvMsg(SubmissionEntry entry, int fd, msghdr msg, MsgFlags flags)

Prepares recvmsg(2) operation.

prepSendMsg

void prepSendMsg(SubmissionEntry entry, int fd, msghdr msg, MsgFlags flags)

Prepares sendmsg(2) operation.

prepSyncFileRange

void prepSyncFileRange(SubmissionEntry entry, int fd, ulong offset, uint len, SyncFileRangeFlags flags)

Prepares sync_file_range(2) operation.

prepTimeout

void prepTimeout(SubmissionEntry entry, KernelTimespec time, ulong count, TimeoutFlags flags)

This command will register a timeout operation.

prepTimeoutRemove

void prepTimeoutRemove(SubmissionEntry entry, D userData)

Prepares operations to remove existing timeout registered using TIMEOUToperation.

prepWriteFixed

void prepWriteFixed(SubmissionEntry entry, int fd, ulong offset, ubyte[] buffer, ushort bufferIndex)

Prepares write_fixed operation.

prepWritev

void prepWritev(SubmissionEntry entry, int fd, V buffer, ulong offset)

Prepares writev operation.

setUserData

void setUserData(SubmissionEntry entry, D data)

Template function to help set SubmissionEntry user_data field.

setup

int setup(Uring uring, uint entries, SetupFlags flags)

Setup new instance of io_uring into provided Uring structure.

Structs

Uring

struct Uring
