XCache - where is serious documentation?

Question

i'm trying to studying XCache but is very difficult to get complete documentation (or also lazy documentation like apc docs).

For example i'd like to know difference beetwen

xcache_list(0, 0);

and

xcache_list(1, 0);

Someone can helps me?

Answer 1

Simple, one fetches stored variables, the other fetches stored PHP pages (OPCODE cached pages):

The better use would be to use the constants:

xcache_list(XC_TYPE_VAR, 0)

and

xcache_list(XC_TYPE_PHP, 0)

As far as the docs, I haven't found anything on that function...
