//! Bindings for the C standard library and other platform libraries
//!
//! **NOTE:** These are *architecture and libc* specific. On Linux, these
//! bindings are only correct for glibc.
//!
//! This module contains bindings to the C standard library, organized into
//! modules by their defining standard.  Additionally, it contains some assorted
//! platform-specific definitions.  For convenience, most functions and types
//! are reexported, so `use libc::*` will import the available C bindings as
//! appropriate for the target platform. The exact set of functions available
//! are platform specific.
//!
//! *Note:* Because these definitions are platform-specific, some may not appear
//! in the generated documentation.
//!
//! We consider the following specs reasonably normative with respect to
//! interoperating with the C standard library (libc/msvcrt):
//!
//! * ISO 9899:1990 ('C95', 'ANSI C', 'Standard C'), NA1, 1995.
//! * ISO 9899:1999 ('C99' or 'C9x').
//! * ISO 9945:1988 / IEEE 1003.1-1988 ('POSIX.1').
//! * ISO 9945:2001 / IEEE 1003.1-2001 ('POSIX:2001', 'SUSv3').
//! * ISO 9945:2008 / IEEE 1003.1-2008 ('POSIX:2008', 'SUSv4').
//!
//! Note that any reference to the 1996 revision of POSIX, or any revs between
//! 1990 (when '88 was approved at ISO) and 2001 (when the next actual
//! revision-revision happened), are merely additions of other chapters (1b and
//! 1c) outside the core interfaces.
//!
//! Despite having several names each, these are *reasonably* coherent
//! point-in-time, list-of-definition sorts of specs. You can get each under a
//! variety of names but will wind up with the same definition in each case.
//!
//! See standards(7) in linux-manpages for more details.
//!
//! Our interface to these libraries is complicated by the non-universality of
//! conformance to any of them. About the only thing universally supported is
//! the first (C95), beyond that definitions quickly become absent on various
//! platforms.
//!
//! We therefore wind up dividing our module-space up (mostly for the sake of
//! sanity while editing, filling-in-details and eliminating duplication) into
//! definitions common-to-all (held in modules named c95, c99, posix88, posix01
//! and posix08) and definitions that appear only on *some* platforms (named
//! 'extra'). This would be things like significant OSX foundation kit, or Windows
//! library kernel32.dll, or various fancy glibc, Linux or BSD extensions.
//!
//! In addition to the per-platform 'extra' modules, we define a module of
//! 'common BSD' libc routines that never quite made it into POSIX but show up
//! in multiple derived systems. This is the 4.4BSD r2 / 1995 release, the final
//! one from Berkeley after the lawsuits died down and the CSRG dissolved.
