bool and BOOL

[Rajesh R Subramanian]

I was just asking where was BOOL defined as an enum. Since the C days, BOOL is an int and even the latest Windows SDK, it is so, to have C compatibility. I have never seen BOOL being defined as an enum in the Windows world.

But it hasn't 8 hexadecimal digits. I.e. I was kidding about your binary numbers prefixed like hexadecimal ones. :)

come on, have you ever worked under linux ? Microsoft IS NOT the standard, even if 85% of the PCs worldwide are windows based... :doh:

Yes, so it is coded 0x00 to 0xFF (hexa representation) or 0b00000000 to 0b11111111 (binary representation).

Yes, why?

So, I don't get the point here. I have worked on development projects on fedora, debian and ubuntu. Linux does not have a BOOL datatype as far as I know. I say - BOOL belongs to Windows. Comments?

BOOL is fully featured integer, for instance, you can do.

// WEIRD BOOL (legal) programming
BOOL b;
b = 1000;
b++;

You can't do the same with a bool variable. [added] Well, I made a sanity check, and actually VC++ compiler gives just a warning on the following code

bool b;
b = 1000; // Warning here (loss of info), at runtime b becomes true.
b++; // at runtime b remains true.

[/added] As stated by someone (Rajesh ? toxcct?) this is a reminiscence of the C language gold ol days (C has not the bool keyword). Using an int to represent Yes/No pair is simply a matter of convention (and convenience). :)

but one has to be careful with BOOL, as I stated at the end of my most here[^]

Indeed. C language implicit mapping of non-zero values to true and zero value to false is more coherent.

Oh come on. You are a "C" lover. I would have expected you to know. :-D
