#.  .I dlopen
#.  Functions marked with

#.  use the dynamic loader to load
#.  shared libraries into the current execution image.
#.  This involves opening files, mapping them into memory,
#.  allocating additional memory, resolving symbols,
#.  applying relocations and more,
#.  all of this while holding internal dynamic loader locks.
#.  The locks are enough for these functions to be AS-Unsafe and AC-Unsafe,
#.  but other issues may arise.
#.  At present this is a placeholder for all
#.  potential safety issues raised by
#.  .BR dlopen (3).
#.  .\" dlopen runs init and fini sections of the module; does this mean
#.  .\" dlopen always implies plugin?
#.  .TP
#.  .I plugin
#.  Functions annotated with
#.  .I plugin
#.  may run code from plugins that
#.  may be external to the GNU C Library.
#.  Such plugin functions are assumed to be
#.  MT-Safe, AS-Unsafe and AC-Unsafe.
#.  Examples of such plugins are stack unwinding libraries,
#.  name service switch (NSS) and character set conversion (iconv) back-ends.
#.  Although the plugins mentioned as examples are all brought in by means
#.  of dlopen, the
#.  .I plugin
#.  keyword does not imply any direct
#.  involvement of the dynamic loader or the
#.  .I libdl
#.  interfaces,
#.  those are covered by
#.  .IR dlopen .
#.  For example, if one function loads a module and finds the addresses
#.  of some of its functions,
#.  while another just calls those already-resolved functions,
#.  the former will be marked with
#.  .IR dlopen ,
#.  whereas the latter will get the
#.  .IR plugin .
#.  When a single function takes all of these actions, then it gets both marks.
#.  .TP
#.  .I i18n
#.  Functions marked with
#.  .I i18n
#.  may call internationalization
#.  functions of the

#.  functions.
#.  This note is thus equivalent to:
#.      | MT-Safe env | AS-Unsafe corrupt heap dlopen | AC-Unsafe corrupt |

#.  .I timer
#.  Functions marked with

#.  In a multi-threaded program, there is a risk that the time-out signal
#.  will be delivered to a different thread,
#.  thus failing to interrupt the intended thread.
#.  Besides being MT-Unsafe, such functions are always
#.  AS-Unsafe, because calling them in signal handlers may interfere with
#.  timers set in the interrupted code, and AC-Unsafe,
#.  because there is no safe way to guarantee an earlier timer
#.  will be reset in case of asynchronous cancelation.

#.  could release it cannot be performed as a single atomic operation.
#.  Similarly,
#.  releasing the descriptor and taking it out of the data structure
#.  normally responsible for releasing it cannot be performed atomically.
#.  There will always be a window in which the descriptor cannot be released
#.  because it was not stored in the cleanup handler argument yet,
#.  or it was already taken out before releasing it.
#.  .\" It cannot be taken out after release:
#.  an open descriptor could mean either that the descriptor still
#.  has to be closed,
#.  or that it already did so but the descriptor was
#.  reallocated by another thread or signal handler.
#.  Such leaks could be internally avoided, with some performance penalty,
#.  by temporarily disabling asynchronous thread cancelation.
#.  However,
#.  since callers of allocation or deallocation functions would have to do
#.  this themselves, to avoid the same sort of leak in their own layer,
#.  it makes more sense for the library to assume they are taking care of it
#.  than to impose a performance penalty that is redundant when the problem

#.  which these functions do not do.
