Local Value Arrays

If the number of new locals to be protected is unknown at compile you can use the following macros that create protected arrays of values. One form creates the array on the stack using _alloc() and so is useful inside one function call, the other puts the array in the heap and so can be used across functions. In both cases, you also need to declare a Value** variable to hold the pointer to the array.

Stack-resident Array

value_local_array - allocates the array of Value* variables
pop_value_local_array - dismisses the array of Value* variables

Heap-resident Array

value_temp_array - allocates the array of Value* variables
realloc_value_temp_array - resizes the array
pop_value_temp_array - dismisses the array

Example

Value** items;
value_local_array(items, n);
for (int i = 0; i < n; i++)
  items[i] = Float::intern(data[i]);
pop_value_local_array(items);
