This is an example of documentation generated by ZigDoc, an alternative to Zig's built-in Auto Doc feature. See also examples in other modes/formats. The project being documented here (as the example) is the Zig standard library. Public Function

write_fixed

Public Function
std.os.linux.IoUring.write_fixed
pub fn write_fixed(
    self: *IoUring,
    user_data: u64,
    fd: linux.fd_t,
    buffer: *posix.iovec,
    offset: u64,
    buffer_index: u16,
) !*linux.io_uring_sqe

Queues (but does not submit) an SQE to perform a IORING_OP_WRITE_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.

Params

  • self: *IoUring
  • user_data: u64
  • fd: linux.fd_t
  • buffer: *posix.iovec
  • offset: u64
  • buffer_index: u16
