<<fgetc_unlocked>> is a non-thread-safe version of <<fgetc>>.
<<fgetc_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
<<fgetc_unlocked>> is equivalent to <<fgetc>>.
The functions <<_fgetc_r>> and <<_fgetc_unlocked_r>> are simply reentrant
versions that are passed the additional reentrant structure pointer
argument: <[ptr]>.

RETURNS
The next character (read as an <<unsigned char>>, and cast to
<<int>>), unless there is no more data, or the host system reports a
read error; in either of these situations, <<fgetc>> returns <<EOF>>.
You can distinguish the two situations that cause an <<EOF>> result by
using the <<ferror>> and <<feof>> functions.
PORTABILITY
ANSI C requires <<fgetc>>.
