DXGetRegularArrayInfo #!N #!N Function #!N #!N Returns the number of items,
the origin, and the delta of a Regular Array. #!N #!N
Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> RegularArray DXGetRegularArrayInfo(RegularArray a, int *count, Pointer
origin, Pointer delta) #!EF #!N #!N Functional Details #!N #!N If
#!F-adobe-times-bold-r-normal--18* count #!EF is not #!F-adobe-times-bold-r-normal--18* NULL #!EF , this routine
returns in #!F-adobe-times-bold-r-normal--18* *count #!EF the number of points. If #!F-adobe-times-bold-r-normal--18*
origin #!EF is not #!F-adobe-times-bold-r-normal--18* NULL #!EF , it returns in
#!F-adobe-times-bold-r-normal--18* *origin #!EF the position of the first point. If #!F-adobe-times-bold-r-normal--18*
delta #!EF is not #!F-adobe-times-bold-r-normal--18* NULL #!EF , it returns in
#!F-adobe-times-bold-r-normal--18* *delta #!EF the spacing between the points. Both #!F-adobe-times-bold-r-normal--18* origin
#!EF and #!F-adobe-times-bold-r-normal--18* delta #!EF must point to buffers large enough
to hold one item of the type of #!F-adobe-times-bold-r-normal--18* a #!EF
. The information about #!F-adobe-times-bold-r-normal--18* a #!EF may be obtained by
calling #!F-adobe-times-bold-r-normal--18* DXGetArrayInfo #!EF . #!N #!N Regular Arrays provide a
compact representation for a sequence of #!F-adobe-times-bold-r-normal--18* count #!EF points beginning
at #!F-adobe-times-bold-r-normal--18* origin #!EF and extending in the direction specified by
the #!F-adobe-times-bold-r-normal--18* delta #!EF vector and spaced #!F-adobe-times-bold-r-normal--18* delta #!EF apart.
The dimensionality of #!F-adobe-times-bold-r-normal--18* origin #!EF and #!F-adobe-times-bold-r-normal--18* delta #!EF may
be found through a call to #!F-adobe-times-bold-r-normal--18* DXGetArrayInfo #!EF . By
accessing the origin and delta information directly, it may be possible
to process Regular Arrays without expansion. Array handles provides a mechanism
for accessing individual elements of a Regular Array without expansion. #!N
#!N Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* a #!EF or returns
#!F-adobe-times-bold-r-normal--18* NULL #!EF and sets an error code. #!N #!N See
