Changes the value at a given index in an array.

Declaration

func CFArraySetValueAtIndex(_ theArray: CFMutableArray!, _ idx: CFIndex, _ value: UnsafeRawPointer!)

theArray:
The array in which the value is to be changed.
idx:
The index at which to set the new value. The value must not lie outside the index space of theArray (0 to N-1 inclusive, where N is the count of the array before the operation).
value:
The value to set in theArray. The value is retained by theArray using the retain callback provided when theArray was created and the previous value at idx is released. If the value is not of the type expected by the retain callback, the behavior is undefined. The indices of other values are not affected.
