Writes an array of count elements, each one with a size of size bytes, from the block of memory pointed by ptr to the current position in the stream. 以二进制的形式将数据块写入文件, 函数原型为: 代码语言:javascript 代码运行次数:0 运
You must then use CArray::Copy and CArray::SetAt to populate the new array because those methods use an assignment operator instead of memcpy_s. As with a C array, the access time for a CArray indexed element is constant and is independent of the array size. Tip Before using an array...
TheCArrayimplementation uses this method to copy the old data to a new buffer when the array should grow or shrink (whenSetSizeorFreeExtraare called). The default implementation just copies the data. For arrays in which an element contains a pointer to one of its own members, or another st...
