Many thanks Felipe, the problem is the exported name(s). The exported names is SCAN_AllocateBuffer_A and SCAN_AllocateBuffer_W.
Thanks again! Gabor Felipe Monteiro de Carvalho írta:
Can you show us the c declaration of the function you are calling? It should be on a .h file. Also, you should put an way to verify if the calls are working, like: DLL_Handle:=LoadLibrary('SCNAPI32.DLL');if DLL_Handle = nil then raise EException.Create('Could not load library');Pointer(SCAN_AllocateBuffer):=GetProcedureAddress(DLL_Handle, 'SCAN_AllocateBuffer'); if Pointer(SCAN_AllocateBuffer) = nil then raise EException.Create('Could not load procedure'); One possibility is that this C library uses name mangling, and the function has a different name from the canonical one. You can check all function names exported by the function using this software: http://wiki.lazarus.freepascal.org/Libview
