- * Macro to free all elements of an XPCOM array of a given size using
- * freeFunc, then frees the array itself using free().
- *
- * Note that this macro (and its wrappers) can be used to deallocate a
- * partially- or completely-built array while unwinding an error
- * condition inside the XPCOM routine that was going to return the
- * array.  For this to work on a partially-built array, your code
- * needs to be building the array from index 0 upwards, and simply
- * pass the number of elements that have already been built (and thus
- * need to be freed) as |size|.
- *
- * Thanks to <alecf@netscape.com> for suggesting this form, which
- * allows the macro to be used with NS_RELEASE / NS_RELEASE_IF in
- * addition to free.
- *
- * @param size      Number of elements in the array.  If not a constant, this
- *                  should be a int32_t.  Note that this means this macro
- *                  will not work if size >= 2^31.
- * @param array     The array to be freed.
- * @param freeFunc  The function or macro to be used to free it.
- *                  For arrays of nsISupports (or any class derived
- *                  from it), NS_IF_RELEASE (or NS_RELEASE) should be
- *                  passed as freeFunc.  For most (all?) other pointer
- *                  types (including XPCOM strings and wstrings),
- *                  free should be used.
