For a macro version of this function, see <<putc>>.
The <<_fputc_r>> function is simply a reentrant version of <<fputc>>
that takes an additional reentrant structure argument: <[ptr]>.
<<fputc_unlocked>> is a non-thread-safe version of <<fputc>>.
<<fputc_unlocked>> may only safely be used within a scope
protected by flockfile() (or ftrylockfile()) and funlockfile(). This
function may safely be used in a multi-threaded program if and only
if they are called while the invoking thread owns the (FILE *)
object, as is the case after a successful call to the flockfile() or
ftrylockfile() functions. If threads are disabled, then
<<fputc_unlocked>> is equivalent to <<fputc>>.
The <<_fputc_r>> and <<_fputc_unlocked_r>> functions are simply reentrant
