Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Pointer DXIterateArray(ArrayHandle handle, int offset, Pointer
last, Pointer scratch) #!EF #!N #!N Functional Details #!N #!N This
routine can be used when an Array is accessed sequentially. The
Array handle #!F-adobe-times-bold-r-normal--18* handle #!EF is that obtained through the use
of #!F-adobe-times-bold-r-normal--18* DXCreateArrayHandle #!EF . #!N #!N If the Array is
constant, a pointer to the constant value is immediately returned. If
the Array is irregular and the given #!F-adobe-times-bold-r-normal--18* offset #!EF is
0, the Array data pointer (which is a pointer to the
0th element of the Array) is returned. If the #!F-adobe-times-bold-r-normal--18* offset
#!EF is not 0, then the #!F-adobe-times-bold-r-normal--18* last #!EF parameter should
point to the prior Array element, and ( #!F-adobe-times-bold-r-normal--18* last #!EF
+ itemSize) is returned, where itemSize is the size in bytes
of an item of the Array described by #!F-adobe-times-bold-r-normal--18* handle #!EF
. If the Array is compact, the desired element is calculated.
#!F-adobe-times-bold-r-normal--18* scratch #!EF should be of a size large enough to
hold a single Array item. #!N #!N Return Value #!N #!N
Returns a pointer to the next item in an Array or
returns #!F-adobe-times-bold-r-normal--18* NULL #!EF (but does not set an error) code
when there are no more items. #!N #!N See Also #!N
