Functions
DAS_API void	das_datum_init (das_datum *pThis, const ubyte *pSrc, das_val_type vt, uint32_t vsize, das_units units)
	General datum initialization.
char *	das_datum_toStrValOnlySep (const das_datum *pThis, char *sStr, size_t uLen, int nFracDigits, const char *sSep)
	Similar to das_datum_toStr, but can specify a separator for vectors.

Function Documentation

das_datum_init()

DAS_API void das_datum_init	(	das_datum *	pThis,
		const ubyte *	pSrc,
		das_val_type	vt,
		uint32_t	vsize,
		das_units	units
	)

General datum initialization.

Parameters

pSrc	A pointer to the source location. If the source bytes are less then DATUM_BUF_SZ they are copied internally, otherwise the pointer itself is stored in the first member of the struct.
vt	The value type, one of the 15 types listed in the das_val_type enum.
vsize	The value size, for anything other then vtUnknown, vtByteSeq and vtText this parameter is ignored.
units	The units associated with the value.

das_datum_toStrValOnlySep()

char * das_datum_toStrValOnlySep	(	const das_datum *	pThis,
		char *	sStr,
		size_t	uLen,
		int	nFracDigits,
		const char *	sSep
	)

Similar to das_datum_toStr, but can specify a separator for vectors.

The separator is ignored if the element type is not multi-valued
