Where is stdbool.h?

Question

I want to find the _Bool definition on my system, so for systems where it\'s missing I can implement it. I\'ve seen various definitions for it here and on other

Answer 1

_Bool is a built-in type, so don't expect to find a definition for it in a header file, even a system header file.

Having said that, guessing your system from the paths that you are searching, have you looked in /usr/lib/gcc/*/*/include ?

My "real" stdbool.h lives there. As expected it #defines bool to be _Bool. As _Bool is a type native to the compiler there's no definition for it in the header file.
