No, filelength is not a Posix function.

The fact that its source is under src/libc/posix does not mean that this 
function is Posix (there are all kinds of helper functions there written 
to be used by Posix functions such as stat and fstat).  If you don't 
trust the docs, look in the header file which defines the prototype 
(io.h, in this case): if the prototype is after this line:

  #ifndef _POSIX_SOURCE

then the function is non-Posix.
