+   Sorts an integer array in ascending or descending order.
+   
+   This function uses the `qsort` function to sort an array of integers either
+   in ascending or descending order, based on the provided `order` argument.
+   The comparison is done using the standard integer comparison logic.
+   
+   @param array Pointer to the integer array to be sorted.
+   @param arrlen The length of the array.
+   @param order A string that specifies the sorting order. It can be:
+                - "asc" for ascending order
+                - "desc" for descending order
+                If an invalid value is provided, the function will print an error message.
+   
+   @note If the `order` parameter is not one of "asc" or "desc", an error message will be printed.
+   @see qsort(3) for the underlying sorting algorithm used.
