Re: [sqlite] sqlite3_create_function callback problem

Ok, I figured it out !!! This was actually a calling convention problem. Our software is built using __fastcall as default convention, and the function in sqlite3.h is declared as: int __cdecl sqlite3_create_function( sqlite3 *, const char *zFunctionName, int nArg, int eTextRep, void*,

Re: [sqlite] sqlite3_create_function callback problem

Sorry I forgot to mention: I already tried single C function. I even tried with extern "C" just in case but got exactly the same result. I also tried __stdcall and __cdecl but looks like SQLite is wayting for __fastcall function pointer On Wed, Dec 17, 2008 at 5:37 PM, Martin Engelschalk

Re: [sqlite] sqlite3_create_function callback problem

Hello, Looks like my last reply wasn't received So I tried with a static function out of a class without more success. Then I tried changing the calling convention to __stdcall and even __cdecl, but I got a compilation error asking for a __fastcall function, so no more success here (I'm

Re: [sqlite] sqlite3_create_function callback problem

Hi, i suspect that you problem is the class MyClass. Try to define your function "ScorePosition" as a C-function outside of a class. Martin Guillaume Schub wrote: > Hi everyone, > > I have spent nearly one day on this already with no success. I am > currently trying to create some custom

[sqlite] sqlite3_create_function callback problem

Hi everyone, I have spent nearly one day on this already with no success. I am currently trying to create some custom function on a SQLite3 database. What I did (just to test): sqlite3_create_function(m_pDB, "ScorePosition", "ScorePosition", 8, SQLITE_ANY, NULL, , NULL, NULL); class MyClass {
