13 * LCLint ISO C + POSIX Library
19 * In 1988, IEEE Std 1003.1-1988, commonly known as "POSIX" or the
20 * "IEEE Portable Operating System Interface for Computing Environments"
21 * was published as an American National Standard. In 1990, IEEE Std
22 * 1003.1-1990 was published as an International Standard. The two
23 * standards differ slightly, and where they do, the 1990 International
24 * standard was used for this lclint library. The differences are:
27 * 1990: -removed- (but still in this lclint library)
29 * 1988: int read (int, void*, unsigned int)
30 * 1990: ssize_t read (int, void*, size_t)
32 * 1988: int write (int, const void*, unsigned int)
33 * 1990: ssize_t write (int, const void*, size_t)
35 * The other differences are in the semantics of functions.
39 * The reference for the ISO C part of this library was
40 * Plauger, Brodie's "Standard C - A Reference", Prentice Hall.
41 * The reference for the POSIX part of this library was
42 * Donald Lewine's "POSIX Programmer's Guide", O'Reilly.
43 * Transcription by Jens Schweikhardt <schweikhardt@rus.uni-stuttgart.de>
47 * Note that Amendment 1 to ISO C was published in 1995 after POSIX was out.
48 * Amendment 1 basically adds support for wide characters and iso 646
49 * source character sets. In particular, there are three new headers:
50 * <iso646.h>, <wchar.h>, and <wctype.h>
54 * Each header has annotations in this order:
56 * 1) type definitions (if any)
57 * 2) constant definitions (if any)
58 * 3) structure definitions (if any)
59 * 4) function prototypes and externals (if any)
61 * 5) type definitions augmented by POSIX (if any)
62 * 6) constant definitions augmented by POSIX (if any)
63 * 7) structure definitions augmented by POSIX (if any)
64 * 8) function prototypes and externals augmented by POSIX (if any)
66 * Builtins are mentioned in the header where they appear according to ISO.
