Function core.memory.GC.sizeOf

Returns the true size of the memory block referenced by p. This value represents the maximum number of bytes for which a call to realloc may resize the existing block in place. If p references memory not originally allocated by this garbage collector, points to the interior of a memory block, or if p is null, zero will be returned.

static ulong sizeOf (
  scope const(void*) p

  void* p
) pure nothrow @nogc;

Parameters

NameDescription
