Re: where `tolower` is implemented when `__OPTIMIZE__` macro is off?


Hi guys,

I'm looking for the place where `tolower` function is defined in
glibc. In `ctype/ctype.h` file I can see it implemented as a
function-like macro but that is guarded by `__OPTIMIZE__` macro. What
happens if __OPTIMIZE__ is not defined? Grepping though the codebase
did not help.

Kind regards,
Alex Yursha
