Question

How to parse in c++ list of null-terminated Unicode strings where the list is terminated with two NULL characters?

Answer 1

There’s this little example on Raymond Chen’s blog (which, perhaps not surprisingly, is the first find in Google for “double null terminated string”):

This reinterpretation of a double-null-terminated string as really a
list of strings with an empty string as the terminator makes writing
code to walk through a double-null-terminated string quite
straightforward:

> for (LPTSTR pszz = pszzStart; *pszz; pszz += lstrlen(pszz) + 1) {  ...
> do something with pszz ... }

The LPTSTR and lstrlen are wrappers which change depending on whether or not _UNICODE is set.
