[Boost-users] [Regex] Simpler load_file code to use in snippet examples?

Thanks for providing and maintaining regex.

The following code is used in a number of the example snippets:

#void load_file(std::string& s, std::istream& is)
#{
#   s.erase();
#   if(is.bad()) return;
#   s.reserve(is.rdbuf()->in_avail());
#   char c;
#   while(is.get(c))
#   {
#      if(s.capacity() == s.size())
#         s.reserve(s.capacity() * 3);
#      s.append(1, c);
#   }
#}

My impression is that this code is used because some compilers won't accept 
a simpler and more direct approach.

I was wondering if the following would work "cross-platform" (It seems to 
work ok with the Microsoft Visual Studio vc7.1 compiler, but I am ignorant 
of other compilers):

#void load_file(std::string& s, std::istream& is)
#{
#   if(is.bad()) return;
#   // Use 0 as CrLf delimiter to cause entire file to be read
#   getline(is, s, '\0');
#}
