- * poll() and pipe() Windows compatibility layer for libusb 1.0
- *
- * The way this layer works is by using OVERLAPPED with async I/O transfers, as
- * OVERLAPPED have an associated event which is flagged for I/O completion.
- *
- * For USB pollable async I/O, you would typically:
- * - obtain a Windows HANDLE to a file or device that has been opened in
- * OVERLAPPED mode
- * - call usbi_create_fd with this handle to obtain a custom fd.
- * Note that if you need simultaneous R/W access, you need to call create_fd
- * twice, once in RW_READ and once in RW_WRITE mode to obtain 2 separate
- * pollable fds
- * - leave the core functions call the poll routine and flag POLLIN/POLLOUT
- *
- * The pipe pollable synchronous I/O works using the overlapped event associated
- * with a fake pipe. The read/write functions are only meant to be used in that
- * context.
