ISO/IEC TR 24731
Abstract
ISO/IEC TR 24731-1:2007 provides alternative functions for the C Library
(as defined in ISO/IEC 9899:1999) that promote safer, more
secure programming. The functions verify that output buffers are
large enough for the intended result, and return a failure indicator
if they are not. Optionally, failing functions call a
"runtime-constraint handler" to report the error. Data is never written
past the end of an array. All string results are null terminated.
In addition, the functions in ISO/IEC TR 24731-1:2007 are re-entrant:
they never return pointers to static objects owned by the function.
ISO/IEC TR 24731-1:2007 also contains functions that address insecurities
with the C input-output facilities.
好像是今年八月出版的？其實我覺得說這是標準也沒錯啦，只是... XD
不清楚 C 有沒有像 C++ 的 boost 那種東西？boost 就有做半套 TR1,
總比完全沒有好 :o
習慣把標準看成 C99, C++98, C++03 等... 所以沒想到 TR
and dinkumware 似乎有以下 TR:
<hardware> [added with TR18015] --
for writing portable I/O hardware drivers in C++
<iohw.h> [added with TR18015/TR18037] --
for writing portable I/O hardware drivers in C
<stdfix.h> [added with TR18037] --
for performing fixed-point arithmetic in C
<uchar.h> [added with TR19769] --
for manipulating 16-bit and 32-bit Unicode wide characters in C
還有 C++ 社群俗稱的 TR1...
不知道全部有多少個？ :o
