DXGetConstantArrayData

Function

Returns a pointer to the value stored in a Constant Array.

Syntax

#include <dx/dx.h>

Pointer DXGetConstantArrayData (Array a)

Functional Details

The data pointed to by this pointer should be interpreted by the user according the type, category, rank, and shape parameters associated with a.

While a Constant Array may contain numerous items, as may be indicated by either DXGetArrayInfo or DXQueryConstantArray, the pointer returned by DXGetConstantArrayData should not be incremented beyond the amount necessary to index a single item since the value of all items in a Constant Array is actually stored in a single item.

For compatibility with previous versions, this routine will also work with Regular Arrays where the delta vectors consist solely of zeros.

Return Value

Returns a pointer to the data contained in the Constant Array or returns NULL and sets an error code.
