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:
