/** Locking
|

|

Locking is loosely controlled by the preprocessor variable

BFD_LOCKS. I say loosely because Unix barely understands locking
|

-- at least in BSD it doesn't affect programs which don't
|

explicitly use it! That is to say it's practically useless, though
|
||||
if everyone uses this library you'll be OK.
|
||||
|
||||
From among the many and varied lock facilities available, (none of
|
||||
which, of course, knows about any other) we use the fcntl locks,
|
||||
because they're Posix.
|
||||
|
||||
The reason that @code{bfd_openr} and @code{bfd_fdopenr} exist, yet
|
||||
only @code{bfd_openw} exists is because of locking. When we do
|
||||
output, we lock the filename file for output, then open a temporary
|
||||
file which does not actually get its correct filename until closing
|
||||
time. This is safest, but requires the asymmetry in read and write
|
||||
entry points.
|
||||
|
||||
Perhaps, since unix has so many different kinds of locking anyway,
|
||||
we should use the emacs lock scheme?... */
