|
|
*
|
|
* ARGUMENT
|
|
* DEC *pSrc[];
|
|
* DEC *pDst;
|
|
* int size;
|
|
*
|
|
* DESCRIPTION
|
|
* Given size DEC pointers stored in the array pSrc, finds the minimum

|
*
|
|
* SIDE EFFECTS
|
|
* None.
|
|
*
|
|
* RETURNS
|
|
* Returns GM_NULL on error, otherwise pDst.

|
*
|
|
* POSSIBLE ERROR CODES
|
|
*
|
|
* GM_NULLPOINTER
|
|
* GM_ARGVAL (when size is 0)
