Here, marshaling as LPArray (C-style array) is fine, but you need SizeParamIndex set to 1 to tell .NET that the length is the second parameter (the zero-based index is 1). If you have a fixed-length array, you can use SizeConst to specify a fixed size—for ex...
15.Bridget Jones is the perfect example of this: it doesn't matter whether she was the best-drawn singleton on the market, any more than it matters whether Karl Marx was the best at communism. 16.Against that reasonable contract, West led his singleton club, and East won and returned a...
那么在Java中的实现与在C/C++中不同吗?是的。 下面的的Java代码是不能够实现Double-Checked Locking模式的: class Printer { privatestatic Printer resource ; publicstatic Printer getInstance(){ if(resource ==null ){ synchronized (DoubleCheckedLockingExample.class) { ...
(C-style array) is fine, but you need SizeParamIndex set to 1 to tell .NET that the length is the second parameter (the zero-based index is 1). If you have a fixed-length array, you can use SizeConst to specify a fixed size—for example, SizeConst = 50 if the ar...
