CArchive对象不仅可以处理首要类型,而且还能处理为串行化而设计的CObject_派生类的对象。一个串行化类通常有一个Serialize成员函数并且使用DECLARE_SERIAL和IMPLEMENT_SERIAL宏。这些在CObject类中有所描述。 重载提取(>>)和插入(<<)是方便的归档编程接口。它支持主要类型和CObject派生类。 CArchive还支持使用MFC Window...

Access Array Elements You can access elements of an array by indices. Suppose you declared an arraymarkas above. The first element ismark[0], the second element ismark[1]and so on. Declare an Array Few keynotes: Arrays have 0 as the first index, not 1. In this example,mark[0]is th...

当有数据要处理时:读取PCM数据(捕捉采集) 或写入PCM数据(回放), 然后关闭音频界面的连接。 */ 把缓冲区的数据引入到数组 (貌似已完成)。LE 或者 BE 的缓冲区数据转换成 INT 或 FLOAT 或 DOUBLE,似乎有点问题,有待进一步学习。端序的问题貌似已经理解。另外内存管理有点复杂, 一不小心就 SEGMENTATION FAULT。
1. Declare Arrays in C/C++ ⮚ Allocate memory on Stack In C/C++, we can create an array, as shown below: 1 intarr[5]; The above code creates a static integer array having size 5. It will allocate the memory on the stack, and the scope of this memory is limited to the scope ...
(An easy way out of this is to declare the string as a static char[] initialized to that value.) The GDB Debugger The GDB debugger is available as part of the Interix Software Development Kit. It is possible Examples Introduction In this section outlines a number of porting examples to ...
Use{{ }}Double Curly Braces to Initialize 2DcharArray in C The curly braced list can also be utilized to initialize two-dimensionalchararrays. In this case, we declare a 5x5chararray and include five braced strings inside the outer curly braces. ...
declare two differently qualified pointers to the same type, int. 6.12.5 Compatible Array TypesFor two array types to be compatible, their element types must be compatible. If both array types have a specified size, they must match, that is, an incomplete array type (see Section 6.11, ...
