You are correct, we don't provide a function to check if a memory are
is all zeros.

We would not add such a function.

Why?

The GNU C Library strives to be a C library, and as such we use the ISO C11
standard as guidance for what to add in the library.

If you think that a function that searches a memory area for all
zeroes is important
then I encourage you to join your national body standards group and work on
the C standard to add this function there.

Once the function is added to the standard we will discuss
implementing it in glibc.

Does that make sense?

Cheers,
Carlos.
