/* @file plustek-pp_types.h
* @brief some typedefs and error codes
*
* Copyright (C) 2000-2013 Gerhard Jaeger <gerhard@gjaeger.de>
*
* History:
* 0.30 - initial version
* 0.31 - no changes
* 0.32 - added _VAR_NOT_USED()
* 0.33 - no changes
* 0.34 - no changes
* 0.35 - no changes
* 0.36 - added _E_ABORT and _E_VERSION
* 0.37 - moved _MAX_DEVICES to plustek_scan.h
* added pChar and TabDef
* 0.38 - comment change for _E_NOSUPP
* added RGBByteDef, RGBWordDef and RGBULongDef
* replaced AllPointer by DataPointer
* replaced AllType by DataType
* added _LOBYTE and _HIBYTE stuff
* added _E_NO_ASIC and _E_NORESOURCE
* 0.39 - no changes
* 0.40 - moved _VAR_NOT_USED and TabDef to plustek-share.h
* 0.41 - no changes
* 0.42 - moved errorcodes to plustek-share.h
* 0.43 - no changes
* 0.44 - define Long and ULong types to use int32_t, so
* the code should still work on 64 bit machines
* .
