Details This routine allocates to Array #!F-adobe-times-bold-r-normal--18* a #!EF the space
for at least #!F-adobe-times-bold-r-normal--18* n #!EF items. It increases efficiency because
it allocates space in advance, eliminating the need to allocate additional
space at a later time. It is most useful when you
can specify the maximum number of items that will be added.
The routine changes only the amount of space allocated to Array
#!F-adobe-times-bold-r-normal--18* a #!EF , not the #!F-adobe-times-medium-i-normal--18* number of items #!EF
in it (only #!F-adobe-times-bold-r-normal--18* DXAddArrayData #!EF can do that). Note: In
the ideal case of knowing the #!F-adobe-times-medium-i-normal--18* exact #!EF number of
items the Array will require, you can call #!F-adobe-times-bold-r-normal--18* DXAddArrayData(a, o,
n, NULL) #!EF , which will allocate the right amount of
space for the specified number of items ( #!F-adobe-times-bold-r-normal--18* n #!EF
). The allocation routine detailed here, on the other hand, is
for creating Arrays when this information is #!F-adobe-times-medium-i-normal--18* not #!EF exact.
#!N #!N Return Value 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 Also
