/* DEC **CopyDecimalArray(pDst,pSrc,n)
|
|
*
|
|
* ARGUMENT
|
|
* pDst is a ptr to the array of destination DEC pointers.
|
|
* pSrc is a ptr to the array of source DEC pointers
|
|
* n is the number of elements in pSrc
|
|
*
|
|
* DESCRIPTION
|
|
* Copies pSrc to pDst. If pDst is null, tries to create a
|
|
* DEC array, then do the copy. If some of the pSrc structures
|
|
* are null, the non-null ones are still copied.
|
|
*
|
|
* SIDE EFFECTS
|
|
* None.
|
|
*
|
|
* RETURNS
|
|
* Returns pointer to the new structure if successful, otherwise
|
|
* returns GM_NULLARR.
|
|
*
|
|
* POSSIBLE ERROR CODES
|
|
*
|
|
* GM_NULLPOINTER
|
|
* GM_ARGVAL
