c++ - Precise mode in Boehm Garbage Collector -

-

i've read on webpage of mono using boehm gc in precise mode. use boehm gc c++, however, have found nothing in documentation or headers indicate precise mode, less how turn on.

any information whether has precise mode default , how turn on, or kind of modification mono developers?

the file doc/gcinterface.html garbage collector (archive here) states:

void * gc_malloc_atomic(size_t nbytes) allocates nbytes of storage. requires (amortized) time proportional nbytes. resulting object automatically deallocated when unreferenced. client promises resulting object never contain pointers. memory not cleared. preferred way allocate strings, floating point arrays, bitmaps, etc. more precise information pointer locations can communicated collector using interface in gc_typed.h in distribution.

it looks there "precise" interface can used.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
