- *   data[1] = event fd,

-// Nonblocking ring suitable for concurrent single-writer, multi-reader access.
-//
-// Readers never block the writer and thus this is a nondeterministically lossy
-// transport in the absence of external synchronization. Don't use this as a
-// transport when deterministic behavior is required.
-//
-// Readers may have a read-only mapping; each reader's state is a single local
-// sequence number.
-//
-// The implementation takes care to avoid data races on record access.
-// Inconsistent data can only be returned if at least 2^32 records are written
-// during the read-side critical section.
-//
-// In addition, both readers and the writer are careful to avoid accesses
-// outside the bounds of the mmap area passed in during initialization even if
-// there is a misbehaving or malicious task with write access to the mmap area.
-//
-// When dynamic record size is enabled, readers use the record size in the ring
-// header when indexing the ring, so that it is possible to extend the record
-// type without breaking the read-side ABI.
-//
-// Avoid calling Put() in a tight loop; there should be significantly more time
-// between successive puts than it takes to read one record from memory to
-// ensure Get() completes quickly. This requirement should not be difficult to
-// achieve for most practical uses; 4kB puts at 10,000Hz is well below the
-// scaling limit on current mobile chips.

-//   * Regular unsigned integer types equivalent to the standard types:
-//     unsigned char, unsigned short, unsigned int, unsigned long,

-//   * char without signed/unsigned qualifiers.
-//   * bool.
-//   * std::vector with value type of any supported type, including nesting.

-// An implementation of std::basic_streambuf backed by a FILE pointer. This is
-// ported from the internal llvm-libc++ support for std::cin. It's really
-// unfortunate that we have to do this, but the C++11 standard is too pendantic
-// to support creating streams from file descriptors or FILE pointers. This
-// implementation uses all standard interfaces, except for the call to
-// std::__throw_runtime_error(), which is only needed to deal with exceeding
-// locale encoding limits. This class is meant to be used for reading system
-// files, which don't require exotic locale support, so this call could be
-// removed in the future, if necessary.
