Compiler Coding Practices 5.77 Boolean type and in C99 C99 introduces the native type _Bool. The associated standard header introduces the macros bool, true and false for Boolean tests. For example: #include bool foo(FILE *str) { bool err = false; ... if (!fflush(str)) { err = true; } ... return err; } Note The C99 semantics for bool are intended to match those of C++. 5.77.1 See also Concepts • New library features of C99 on page 5-79.

Compiler Coding Practices 5.78 Extended integer types and functions in and in C99 In C90, the long data type can serve both as the largest integral type, and as a 32-bit container. C99 removes this ambiguity through the new standard library header files and . The header file introduces the new types: • intmax_t and uintmax_t, that are maximum width signed and unsigned integer types • intptr_t and unintptr_t, that are integer types capable of holding signed and unsigned object pointers. The header file provides library functions for manipulating values of type intmax_t, including: intmax_t imaxabs(intmax_t x); // absolute value of x imaxdiv_t imaxdiv(intmax_t x, intmax_t y) // returns the quotient and remainder // of x / y These header files are also available in C90 and C++. 5.78.1 See also Concepts • New library features of C99 on page 5-79.
