relinquish thread ownership of a file
void funlockfile(FILE file);
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.
