I'm trying to implement Spotlight through declares but I have a
memory leak with every query I launch.
AFAIK I declare only one function that allocates memory hence I
presume that should be the only one to release. When I try to
release it however, my application just crashes.
Here's the function that allocates memory:
MDQueryRef MDQueryCreate (
CFAllocatorRef allocator,
CFStringRef queryString,
CFArrayRef valueListAttrs,
CFArrayRef sortingAttrs
);
After I execute the query and store its results, I'm done with it
and want to release the memory:
CFRelease MDQueryRef
This gives a hard crash.
If anybody can give me any clue, like do I release it too soon, do
I have to do something else to release it, are there some
dependencies I'm not aware of, etc.
This looks like it should work. A correct declaration for CFRelease
is the following.
soft declare sub CFRelease lib "Carbon.framework" (cf as Integer)
CFRelease does not like being passed a null pointer, so that's the
first thing I suggest checking.
