/* DEC **SortDecimal(dst, src, n, opt);
|
|
*
|
|
* ARGUMENT
|
|
* DEC **dst;
|
|
* DEC **src;
|
|
* int n;
|
|
* int opt;
|
|
*
|
|
* DESCRIPTION
|
|
* Sorts an array in increasing or decreasing order. The n elements
|
|
* of src are sorted and stored in dst. opt is GM_INC if the elements
|
|
* should be sorted in increasing order, and opt is GM_DEC is the elements
|
|
* should be sorted in decreasing order.
|
|
* A temporary copy of the array is allocated by this procedure.
|
|
*
|
|
* SIDE EFFECTS
|
|
* None.
|
|
*
|
|
* RETURNS
|
|
* dst if successful, otherwise GM_NULL
|
|
*
|
|
* POSSIBLE ERRORS
|
|
* GM_NULLPOINTER
|
|
* GM_INIT
|
|
* GM_NOMEMORY
