如何打印PBYTE的内容? [英] How to print out the contents of a PBYTE?

问题描述

我了解 PBYTE 是 Windows数据类型.

我希望能够使用 printf()或 cout 打印所有内容:

I want to be able to print all the contents, either using printf() or cout:

PBYTE buffer;
ULONG buffersize = NULL;
serializeData(data, buffer, buffersize); 
//this function serializes "data" and stores the data in buffer and updates bufferSize).. 

您能帮助我了解如何在C ++中打印吗?

Can you help me understand how to print this in C++?

推荐答案

如果要打印 buffer 指向的内存地址，则可以执行此操作像这样:

If you want to print the memory address that buffer is pointing at, then you can do it like this:

PBYTE buffer;
ULONG buffersize = 0;
serializeData(data, buffer, buffersize); 
//this function serializes "data" and stores the data in buffer and updates bufferSize)...

printf("%p", buffer);
or
std::cout << (void*)buffer;

...

但是，如果要打印缓冲区的内容，则需要遍历缓冲区并分别打印出每个 BYTE ，例如:

But, if you want to print the contents of the buffer, you need to loop through the buffer and print out each BYTE individually, eg:

PBYTE buffer;
ULONG buffersize = 0;
serializeData(data, buffer, buffersize); 
//this function serializes "data" and stores the data in buffer and updates bufferSize)...

for (DWORD i = 0; i < buffersize; ++i)
{
    printf("%02x ", buffer[i]);
    or
    std::cout << std::hex << std::setw(2) << std::setfill('0') << (unsigned int)buffer[i] << " ";
}

...
