Re: [xml] Possible error reporting addition to the library

[Aleksey Sanin <aleksey aleksey com>]

There are two more possible options:
   3) If caller cares about error code let caller write an *application 
specific*
   error callback that stores the last error code on per-thread basis 
(using
   TLS or whatever). On LibXML side this means a new error reporting
   function that has all the necessary parameters (error code, etc.) and
   replacing all the current xmlError(..) calls with calls to new function.
   This is a boring task but it's relatevly safe and easy for LibXML 
itself.

   4) Write all the code to handle threads correctly by yourself (using 
TLS,
   for example). However, I would not volunteer to support such piece 
of code
   because it quickly becomes a nightmare (each OS has its own "features").
