- * @file
- * @author Ruby developers <ruby-core@ruby-lang.org>
- * @copyright This file is a part of the programming language Ruby.
- * Permission is hereby granted, to either redistribute and/or
- * modify this file, provided that the conditions mentioned in the
- * file COPYING are met. Consult the file for details.
- * @warning Symbols prefixed with either `RUBY3` or `ruby3` are
- * implementation details. Don't take them as canon. They could
- * rapidly appear then vanish. The name (path) of this header file
- * is also an implementation detail. Do not expect it to persist
- * at the place it is now. Developers are free to move it anywhere
- * anytime at will.
- * @note To ruby-core: remember that this header can be possibly
- * recursively included from extension libraries written in C++.
- * Do not expect for instance `__VA_ARGS__` is always available.
- * We assume C99 for ruby itself but we don't assume languages of
- * extension libraries. They could be written in C++98.
- * @brief Public APIs to provide ::rb_fd_select().
- *
- * Several Unix platforms support file descriptors bigger than FD_SETSIZE in
- * `select(2)` system call.
- *
- * - Linux 2.2.12 (?)
- *
- * - NetBSD 1.2 (src/sys/kern/sys_generic.c:1.25)
- * `select(2)` documents how to allocate fd_set dynamically.
- * http://netbsd.gw.com/cgi-bin/man-cgi?select++NetBSD-4.0
- *
- * - FreeBSD 2.2 (src/sys/kern/sys_generic.c:1.19)
- *
- * - OpenBSD 2.0 (src/sys/kern/sys_generic.c:1.4)
- * `select(2)` documents how to allocate fd_set dynamically.
- * http://www.openbsd.org/cgi-bin/man.cgi?query=select&manpath=OpenBSD+4.4
- *
- * - HP-UX documents how to allocate fd_set dynamically.
- * http://docs.hp.com/en/B2355-60105/select.2.html
- *
- * - Solaris 8 has `select_large_fdset`
- *
- * - Mac OS X 10.7 (Lion)
- * `select(2)` returns `EINVAL` if `nfds` is greater than `FD_SET_SIZE` and
- * `_DARWIN_UNLIMITED_SELECT` (or `_DARWIN_C_SOURCE`) isn't defined.
- * http://developer.apple.com/library/mac/#releasenotes/Darwin/SymbolVariantsRelNotes/_index.html
- *
- * When `fd_set` is not big enough to hold big file descriptors, it should be
- * allocated dynamically. Note that this assumes `fd_set` is structured as
- * bitmap.
- *
- * `rb_fd_init` allocates the memory.
- * `rb_fd_term` frees the memory.
- * `rb_fd_set` may re-allocate bitmap.
- *
- * So `rb_fd_set` doesn't reject file descriptors bigger than `FD_SETSIZE`.
