+<pre>! Proposal:
+We need some centralized way to handle errors and doing hard aborts.
+
+I started using C-string addresses as errors for now, I think that convinient and unique until we find something better. (Actually this might be even kept in a library, alternatively maybe someone wants to investigate libcomerr)
+
+The next point is allocation failures, these are possible by C/C++ standard but don't actually happen anymore in linux (except in few rare cases). Instead gracefully handling this errors i'll add a {{{CINELERRA_DIE(message)}}} macro to this library later. This macro will just do (NoBug) logging and then doing a hard abort. Macro, because we want to preserve file/line location for logging.

 These things are:
 * [[a Plugin loader|Plugins]]
+* [[ErrorHandling]]
 * a wraper for POSIX Threads
 ** Thread creation joining and canceling
 ** Locking primitives like Condition variables and Mutexes
