Reading .txt file saved in memory

Question

I have a .txt file saved in memory ( void *Buffer; UINT itsLen ). Is there any easy way to read this text file like std::wifstream read txt from a disk?

Answer 1

Yes; use a string stream.

#include <string>
#include <sstream>

...

wchar_t* p = static_cast<wchar_t*>(Buffer);
std::wistringstream s(std::wstring(p, p + itsLen/sizeof(wchar_t)));

The string stream s can be used similarly to a std::wifstream object.
