NAME
funlockfile - relinquish thread ownership of a file
SYNOPSIS
#include <stdio.h>
void funlockfile(FILE *file);
DESCRIPTION
This function provide for explicit application-level locking
of standard I/O objects. It can be used by a thread to end a
sequence of I/O statements that are to be executed as a unit.
funlockfile relinquishes ownership granted to the thread via a
previous successful call to flockfile or ftrylockfile.
A thread can nest calls to flockfile or ftrylockfile as long
as each successful call has a corresponding funlockfile call
to relinquish ownership completely.
The behavior is undefined if funlockfile is called without a
matching successful call to flockfile or ftrylockfile.
