hi,
Hi yang,
'bool' is not a keyword in the C programming language. To use it, make sure you include stdbool.h:
#include <stdbool.h>
in your sources.
I hope this helps,
Erich
thanks, the problem is solved with your help.
An unanswerable question is why is it 'bool' and not 'bool_t' to match <stdint.h> types?
Inconsistencies like this are annoying.
stdbool.h defines bool as a macro because the C standard 7.18
stdint.h defines intN_t as typedefs because the C standard 7.20
You can use one or the other to achieve the same effect, but it's better to use the proper one to your needs, you need to consider the compatibility of the your project.

Daniel.
The point is 'bool' is used as a type, it should end with a _t.
The heading of 7.16 clearly states 'bool' is a type:
"7.16 Boolean type and values".
By convention macros in C are upper case then by 7.18 it should
be BOOL, or properly BOOL_T.
We may be looking at different version of the standard as the one I'm looking at has 7.20 as:
7.20 General utilities <stdlib.h>
