fn read_fixed(self: *IO_Uring, user_data: u64, fd: os.fd_t, buffer: *os.iovec, offset: u64, buffer_index: u16) !*linux.io_uring_sqe

Queues (but does not submit) an SQE to perform a IORING_OP_READ_FIXED. The buffer provided must be registered with the kernel by calling register_buffers first. The buffer_index must be the same as its index in the array provided to register_buffers.

Returns a pointer to the SQE so that you can further modify the SQE for advanced use cases.

Parameters

self: *IO_Uring,
user_data: u64,
fd: os.fd_t,
buffer: *os.iovec,
offset: u64,
buffer_index: u16,
