Question

I have this code that reads from stdin into a char*. Is it possible to do this directly into a std::string?

int size = std::atoi(m_content_size);
char* buffer;
buffer = (char*)malloc(size);
fread(buffer, 1, size, stdin);

...

free(buffer);

I suppose I could do std::string sBuffer(buffer), but I’m hoping there is a better alternative.

Thank you.

You should probably read into a vector of chars or so, just so as to not give the impression that you have “text” if you really have arbitrary binary data:

#include <iostream>
#include <vector>

// ...

std::vector<char> buf(size);
std::cin.read(buf.data(), buf.size());

// all done, will clean up after itself!
