For that to be true, wouldn't you need *CNOWIDEN on the prototype for the
call? Otherwise it's integer, right?
I doubt that *CNOWIDEN would work. I don't know what "bool" means, but
I doubt that a bool is a character value where "true" is '1' (x'F1') or
"false" is '0' (x'F0'). More likely that a bool is integer-ish, and
"false" is 0 and "true" is 1 (or maybe "true" is anything-but-zero since
that's how C currently handles numeric values used in a boolean way).
What *CWIDEN does is widen 1-byte character, and 1- and 2- byte (signed
or unsigned) integers, and 2-byte UCS-2 and DBCS to be passed as 4-byte
(signed or unsigned) integers, and 4-byte floats to be passed as 8-byte
floats. *CNOWIDEN says not to do any widening, but to handle 1-byte
character as 1-byte unsigned integer and 2-byte UCS-2 or DBCS as 2-byte
unsigned integer).
