Standards, Docs, etc.

This is a fine collection of references to documentations about programming and API standards. Especially public available resources, since unfortunately most offical standard documents are not distributed for free :-(

Official Standard Documents

Well, often the "real official" standard documents are rather expensive. So the "clever" people know where the final drafts can be found ... (and they are aware that those are not the final standard documents!)

C
- ANSI C9X standard drafts
  [link is not really broken, but a completly different site shows up nowadays]
- ANSI C standard drafts
- C FAQ (older version in HTML)
C++
- ANSI C++ standard drafts
- C++ FAQ
Fortran
un*x & Other API References
- POSIX.1
  There's no legal copy available for free
- Austin Group standard drafts:
  X/Open and POSIX join now to create a unique definition. You can get the drafts for free if you register (at no cost)! Latest is draft 4.
- un*x man pages (Single UNIX Specification)
- API, standards reference table
- FAQ for un*x programming
Library API References
Misc Programming
- Infos about floating point math, IEEE 754, etc.
- Drafts for ISO/IEC 10967-1 (standard for language-independent arithmetic (LIA-1))

Implementations

Sometimes it might helpful to see a real-world examples of the standards given above. So I also collect some links to implementations. Take to care to read the according docs, which (hopefuly) will tell you about the conformance with according standards.

Misc un*x Stuff
- Useful UNIX links
- Information about various un*x flavours
BSD Systems
linux
Sources, Libraries
- Freely Distributable LIBM (fdlibm)
  Missing math stuff can be found here
- cephes
  Math library, too

Definitions

The following list is taken from the linux man pages (INTRO(2) linux Programmer's Manual), which is not up-to-date. So I will correct&update it when I find some time ...
