Question

Is there a way to get the “raw” buffer o a std::string?
I’m thinking of something similar to CString::GetBuffer(). For example, with CString I would do:

CString myPath;  
::GetCurrentDirectory(MAX_PATH+1, myPath.GetBuffer(MAX_PATH));  
myPath.ReleaseBuffer();  

So, does std::string have something similar?

Answer 1

Use std::vector<char> if you want a real buffer.

#include <vector>
#include <string>

int main(){
  std::vector<char> buff(MAX_PATH+1);
  ::GetCurrentDirectory(MAX_PATH+1, &buff[0]);
  std::string path(buff.begin(), buff.end());
}
