Function Documentation

das_rng2shape()

int das_rng2shape	(	int	nRngRank,
		const ptrdiff_t *	pMin,
		const ptrdiff_t *	pMax,
		size_t *	pShape
	)

Calculate a strided array shape from a min/max range.

Used to calculate the memory requirements for a subset of a strided array range. The output range will often have fewer axes than the the input shape. This is common when slicing.

Parameters

	nRngRank	The length of the min an max location arrays
	pMin	The inclusive lower bound for the range in each array dimension.
	pMax	The exclusive upper bound for the range in each array dimension. For each element of pMax that is just 1 value larger than pMin the output shape is collapsed by one dimension.
[out]	pShape	The output range. Not that if the return rank is 0 then this has no usable elements. At most nRngRank elements will be written into pShape.

Returns

The rank of the shape. This can be 0 if the given range collapses to a single value. Returns -1 if pMin or pMax are invalid (also calls das_error, so the function may not return at all).
