Hi. comctl32 exports (undocumented) Alloc() and friends which call LocalAlloc => GlobalAlloc => HeapAlloc since it's doesn't use any fancy LMEM / GMEM flags... so shouldn't Alloc() call HeapAlloc() directly?
If Global/Local* behave different than Heap* on Windows - wouldn't it then be desirable to replace the Alloc()/etc. calls in our comctl32 (we use it all over the place) by Heap*?
Reason I'm asking: Since it's not documented the Free(NULL) semantics are not clear (although it's safe in our implementation) - and I'm wondering if we really want to internally use undocumented functions with unclear semantics when there is an easy (documented) way.
And besides - the comctl32 code is full of "if(p) Free(p);"...
Looks like i need to add Free() to my redundant_null_check.pl Smatch script.
