Function `rt.lifetime._d_arraysetcapacity`

Set the array capacity.


						
				extern(C) ulong _d_arraysetcapacity
				(
				

				  const(TypeInfo) ti,
				

				  ulong newcapacity,
				

				  void[]* p
				

				);

If the array capacity isn't currently large enough to hold the requested capacity (in number of elements), then the array is resized/reallocated to the appropriate size.

Pass in a requested capacity of 0 to get the current capacity.

Parameters

Name	Description
ti	type info of element type
newcapacity	requested new capacity
p	pointer to array to set. Its `length` is left unchanged.

Returns

the number of elements that can actually be stored once the resizing is done
