Hi, I'm using static linking with Delphi and a new function required binding in 3.7.10 - msize (__msize). The problem here is that there's no official way to query the size of a memory block in Delphi memory manager, at least I'm not aware of one. Should I solve this anyway (for example by keeping my own list of blocks and their sizes) or is there some other solution (enabled/disable some define)?

Quoting and answering myself )
CMIIW, but it seems that HAVE_MALLOC_USABLE_SIZE can't control anything on Windows. As I suppose it's a new define introduced in 3.7.10
Although there are plenty of lines where #ifdef SQLITE_MALLOCSIZE assumes there's a possibility that it either exists or not, but if I don't define anything these lines forces HAVE_MALLOC_USABLE_SIZE to 1 on windows // ------------------ #if !defined( HAVE_MALLOC_USABLE_SIZE) && SQLITE_OS_WIN # define HAVE_MALLOC_USABLE_SIZE 1 # define malloc_usable_size _msize #endif // ------------------
But looks like on other platforms the define is effective ( because ".... && SQLITE_OS_WIN" makes this forcing disabled) and the following line obeys the setting afterwards //--------------------- #ifdef HAVE_MALLOC_USABLE_SIZE #include <malloc.h> #define SQLITE_MALLOCSIZE(x) malloc_usable_size(x) #else #undef SQLITE_MALLOCSIZE #endif //-------------

Try using the trunk of the SQLite source tree with the SQLITE_WITHOUT_MSIZE preprocessor macro.

Richard, thank, I will try, but I just tried to replace

Richard, thanks, tried trunk, everything works, also saw the comment in the sources about automatic usage of msize on Windows. So probably having HAVE_MALLOC_USABLE_SIZE always defined on Windows is necessity.
