Quote:
"bool" is not "standard" C/C++ type

Well... Fundamental types - cppreference.com[^], Boolean type support library - cppreference.com[^].


Quote:
thus if(condition == 0) would make better sense
then if(condition)

most "well written functions return x" , x being mostly zero when function is successful
when function fails – the return value is (generally) -1 or positive value identifying the error
then same as above - if(function (z) == 0) should prevail.

In C++, if a function returns a bool then using
if ( function(x) )
is the only meaningful way I see.

On the other hand, if the function returns an integer data type, then
if (function(x) == expected_int_result)
is the most sensible approach.
