Macro Definition Documentation

#define DT_VXWORKS_APP ( name )

Value:

int main(int argc, char** argv); \
int name(char* cmdLine) \
{ \
   return realMain(DtArgc(cmdLine), DtArgv(cmdLine)); \
}

#define DtATOI ( s ) (int)strtol(s, 0, 0)

some versions of strtol returns INT_MAX for input larger than 0x7fffffff.

As long as strtoul accepts and properly processes negative input, this macro will work for both unsigned and signed ints (as other strtol do).

#define DtDELETE_VOID	(	x,
		cast
	)

Value:

if (x) \
   { \
      cast* toDelete = reinterpret_cast<cast*>(x); \
      delete toDelete; \
      x = 0; \
   }

#define DtISOFF	(	a,
		x
	)	(!DtISON(a, x))

#define DtISON	(	a,
		x
	)	(a & x)

#define DtNUMBER ( foo ) (sizeof(foo)/sizeof(foo[0]))

#define DtOFFSET	(	type,
		field
	)	((size_t)&((type *)NULL)->field)

#define DtSIZEOF	(	type,
		field
	)	sizeof(((type *)NULL)->field)

#define DtTURNOFF	(	a,
		x
	)	(a &= ~x)

#define DtTURNON	(	a,
		x
	)	(a \|= x)

void bzero	(	char *	b,
		int	length
	)

Need bzero.

char** DtArgv	(	char *	cmdLine,

	)

int DtResizeString	(	char *&	buf,
		int &	oldLn,
		int	newLn
	)

For VXWORKS.

void printHexToStream	(	std::ostream &	stream,
		unsigned int	numberOfColumns,
		unsigned char *	ptr,
		unsigned int	bytes
	)

Prints Hex to a stream based on an address and the bytes.

This is primarily used for debugging rather than for anything else.
