/** @file | |
Macros to simplify boolean expressions and operations. | |
This header is not specified by the C95 standard but is included here for | |
operational convenience. | |
The macro bool expands to _Bool, as required by the C99 specification. | |
This subsequently expands to BOOLEAN, is a UEFI data type which is automatically | |
defined correctly for the target CPU architecture. | |
The remaining three macros are suitable for use in #if preprocessing | |
directives. They are true, which expands to the integer constant 1, | |
false, which expands to the integer constant 0, and | |
__bool_true_false_are_defined which expands to the integer constant 1. | |
A program may undefine and perhaps then redefine the | |
macros bool, true, and false. | |
