stdbool.h

Go to the documentation of this file.

 
/*===---- stdbool.h - ClangTool workaround header --------------------------===
 *
 * This is a simplified stdbool.h that doesn't use __has_include_next.
 * ClangTool/LibTooling has a bug where __has_include_next errors instead of
 * returning false when a header doesn't exist. This causes the standard
 * clang stdbool.h to fail on macOS.
 *
 * This header provides the same functionality as the standard stdbool.h
 * without the problematic __has_include_next check.
 *
