#!F-adobe-helvetica-medium-r-normal--18*

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
