Hello and many thanks for answer. The library is SoundTouch.dll and libSoundTouch.so from : >> http://www.surina.net/soundtouch/ >>>Here part of working code (if i call soundtouch_createInstance, it works) ... uses Windows ; ... var soundtouch_createInstance : function() : THandle; stdcall; ... procedure InitLib(LibFile : PAnsiChar); begin LibHandle := LoadLibrary(LibFile); if LibHandle <> 0 then Pointer(soundtouch_createInstance) := GetProcAddress(LibHandle, PAnsiChar('soundtouch_createInstance')); ///////////////////// >>> Here part of NOT working code (if i call soundtouch_createInstance, it >>> crash) ... uses dynlibs ; ... var soundtouch_createInstance : function() : THandle; stdcall; ... procedure InitLib(LibFile : PAnsiChar); begin LibHandle:=DynLibs.LoadLibrary(libfilename); if LibHandle <> DynLibs.NilHandle then Pointer(soundtouch_createInstance) := DynLibs.GetProcedureAddress(LibHandle, PAnsiChar('soundtouch_createInstance')); ///////////////////// Many thanks.
