routine

Called when the operation has completed; required.

Syntax

IoCompletionRoutine routine;

buffer

The data, or the structure the operation names (see IoOperation).

Syntax

void* buffer;

offset

The file offset of Read and Write; see IoOperation for the others; else 0.

Syntax

std::uint64_t offset;

fd

The file or socket.

Syntax

std::int32_t fd;

length

The number of bytes, or the size of what buffer points to.

Syntax

std::uint32_t length;

flags

The flags of the operation (see IoOperation); else 0.

Syntax

std::uint32_t flags;

operation

The operation.

Syntax

IoOperation operation;

reserved8

Belongs to the core; 0 before the request is submitted.
