Macros
Technical declarations for the DLL interface
#define	EXTC   extern
	For use with C.
#define	TDC_CC   __stdcall
	Calling convention.
#define	TDC_API   EXTC __declspec(dllimport)
	External DLL interface.
Return values of the functions
All functions of this lib - as far as they can fail - return one of these constants for success control.
#define	TDC_Ok   0
	Success.
#define	TDC_Error   (-1)
	Unspecified error.
#define	TDC_Timeout   1
	Receive timed out.
#define	TDC_NotConnected   2
	No connection was established.
#define	TDC_DriverError   3
	Error accessing the USB driver.
#define	TDC_DeviceLocked   7
	Can't connect device because already in use.
#define	TDC_Unknown   8
	Unknown error.
#define	TDC_NoDevice   9
	Invalid device number used in call.
#define	TDC_OutOfRange   10
	Parameter in function call is out of range.
#define	TDC_CantOpen   11
	Failed to open specified file.
#define	TDC_NotInitialized   12
	Library has not been initialized.
#define	TDC_NotEnabled   13
	Requested feature is not enabled.
#define	TDC_NotAvailable   14
	Requested feature is not available.

Portable data types
Integer data types of well defined byte length. double is portable by itself. bool is defined in C99 but not supported by all relevant compilers - we use our own type for clarification of interfaces.
#define	LLXFORMAT   "I64x"
	64 bit hex printf format
#define	LLDFORMAT   "I64d"
	64 bit dec printf format
typedef __int8	Int8
	8 bit integer for MSVC
typedef __int32	Int32
	32 bit integer for MSVC
typedef __int64	Int64
	64 bit integer for MSVC
typedef unsigned __int8	Uint8
	8-Bit unsigned int for MSVC
typedef __int32	Bln32
	integer used as boolean
