Very carefully.

It didn't use to be handled at all and there used to be problems with improper
compliance. I wouldn't be surprised if it still happens.

Right now, you have *both* the C++ library and the C libraries working around
this. libstdc++ cstring defines its own std::strchr and memchr as inline
functions, that call a compiler intrinsic. libc++'s don't and they instead
require that the C library's string.h have the proper C++ definitions.

glibc's string.h does define C++ overloads for strchr, strrchr and memchr by
using symbol renaming. Bionic's string.h does not... so is this even working
on today's Android NDK?
