Catching Integer Overflows in C
Update 20150422: clang and gcc 5 have builtins now for this, look for __builtin_add_overflow and __builtin_mul_overflow in the documentation. That makes these macros obsolete. Note: This document and the macros make two important assumptions: There are 8 bits in a char. This is not guaranteed by the C standard, and is in fact not true on all platforms, most notably some ancient mainframes. You cou

Enquire: Everything you wanted to know about your C Compiler and Machine, but didn't know who to ask Steven Pemberton, CWI, Amsterdam. This is a program that determines many properties of the C compiler and machine that it is run on, such as minimum and maximum [un]signed char/int/long, many properties of float/ [long] double, and so on. As an option it produces the ANSI C float.h and limits.h fil
