StdLib/Include/stdbool.h

   1 /** @file
   2   The header <stdbool.h> defines four macros: bool, true, false,
   3   and __bool_true_false_are_defined.
   4
   5   The macro bool expands to _Bool.
   6
   7   The remaining three macros are suitable for use in #if preprocessing
   8   directives. They are true, which expands to the integer constant 1,
   9   false, which expands to the integer constant 0, and
  10   __bool_true_false_are_defined which expands to the integer constant 1.
  11
  12   A program may undefine and perhaps then redefine the
  13   macros bool, true, and false.
