c++ - 遍历 boost mapped_region/memory-mapped 文件？

Question

我有以下代码将文件加载到 boost mapped_region 中：

file_mapping fm(FilePath, read_only);
mapped_region region(fm, read_only);
char * const data = static_cast<char *>(region.get_address());

• 我将如何逐个字符地遍历获得的数据？
• 有什么办法可以修改上面的代码，所以我不使用char*指针，而是使用静态字符数组char c[x]？

Answer 1

file_mapping fm(FilePath, read_only);
mapped_region region(fm, read_only);
char * const data = reinterpret_cast<char*>(region.get_address());

// Iterate through the data obtained, character (c) by character.
for(std::size_t n = 0; n < region.get_size(); ++n)
{
      char c = data[n];
}
