Crate libc + + [−] + + [src]
+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.
