Function Allocates space for the data items of an Array.
Syntax
#include <dx/dx.h> Array DXAllocateArray(Array a, int n).
Functional Details This routine allocates to Array a the space for at least n 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 a, not the number of items in it (only DXAddArrayData can do that).
Note: In the ideal case of knowing the exact number of items the Array will require, you can call DXAddArrayData(a, o, n, NULL), which will allocate the right amount of space for the specified number of items (n). The allocation routine detailed here, on the other hand, is for creating Arrays when this information is not exact.
Return Value Returns a or returns NULL and sets an error code.
