-All functions shown above:
-.nf
-    /* Since glibc 2.24: */ _POSIX_C_SOURCE >= 199309L

-.SH DESCRIPTION
-The stdio functions are thread-safe.
-This is achieved by assigning
-to each
-.I FILE
-object a lockcount and (if the lockcount is nonzero)
-an owning thread.
-For each library call, these functions wait until the
-.I FILE
-object
-is no longer locked by a different thread, then lock it, do the
-requested I/O, and unlock the object again.
-.P
-(Note: this locking has nothing to do with the file locking done
-by functions like
-.BR flock (2)
-and
-.BR lockf (3).)
-.P
-All this is invisible to the C-programmer, but there may be two
-reasons to wish for more detailed control.
-On the one hand, maybe
-a series of I/O actions by one thread belongs together, and should
-not be interrupted by the I/O of some other thread.
-On the other hand, maybe the locking overhead should be avoided
-for greater efficiency.
-.P
-To this end, a thread can explicitly lock the
-.I FILE
-object,
-then do its series of I/O actions, then unlock.
-This prevents
-other threads from coming in between.
-If the reason for doing
-this was to achieve greater efficiency, one does the I/O with
-the nonlocking versions of the stdio functions: with
-.BR getc_unlocked (3)
-and
-.BR putc_unlocked (3)
-instead of
-.BR getc (3)
-and
-.BR putc (3).
-.P
-The
-.BR flockfile ()
-function waits for
-.I *filehandle
-to be
-no longer locked by a different thread, then makes the
-current thread owner of
-.IR *filehandle ,
-and increments
-the lockcount.
-.P
-The
-.BR funlockfile ()
-function decrements the lock count.
-.P
-The
-.BR ftrylockfile ()
-function is a nonblocking version
-of
-.BR flockfile ().
-It does nothing in case some other thread
-owns
-.IR *filehandle ,
-and it obtains ownership and increments
-the lockcount otherwise.
-.SH RETURN VALUE
-The
-.BR ftrylockfile ()
-function returns zero for success
-(the lock was obtained), and nonzero for failure.
-.SH ERRORS
-None.
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
