Question about xmlCleanupParser()

Hi,

I'm having a crash when I call xmlCleanupParser() and I've
some doubts about the use of this function.

I'm developing a library that loads and uses libxml, and I
call xmlCleanupParser in the destructor/DllMain of the
library, when I'm finished using it.

The question is: if someone uses my library and also uses
libxml by his own in a process, my call to xmlCleanupParser
would affect the other instance of libxml?

Thanks in advance,

	Unai

yes, so don't call it, at worse you will just lost a bit of
data global to the
library.

It all depends on how you link libxml2.

If you link dynamically, this may cause problems if the
client code
links dynamically with a more recent (or older) libxml2, and
your
call to xmlCleanupParser could affect your client code.

If you link statically, there is no problem - all calls are
resolved
when building your DLL, so there should be no unexpected
interaction
with client code.

To me, this makes static linkage seem like the best approach
for using
libxml in a DLL.
