opening files were name contains '

[LMHmedchem]

I have a cpp app that reads in a number of files and writes revised output. The app doesn't seem to be able to open a file with a ' in the file name, such as,

N,N'-dimethylethylenediamine.mol

I have been using this app for a while and I think I would have noticed this, but I haven't. Is there some reason why there would be a problem with the file name?

This is the function that opens the file,

// opens mol file, reads in rows to string vector and returns vector
vector<string> get_mol_file(string& filePath) {

   vector<string> mol_file;
   string new_mol_line;

   // create an input stream and open the mol file
   ifstream read_mol_input;
   read_mol_input.open( filePath.c_str() );

   // check if the file was opened
   if(!read_mol_input.is_open()) {
      cout << "mol file  " << filePath << "  could not be opened" << endl;
      exit(-3);
   }

   // add each keep line to mol_file
   while(getline(read_mol_input, new_mol_line)) {
      // remove windows '\r' character if present
      new_mol_line.erase (remove(new_mol_line.begin(),new_mol_line.end(),'\r') , new_mol_line.end());
      // store keep values in vector
      mol_file.push_back(new_mol_line);
   }

return mol_file;
}

The path to the file is passed as a cpp string and the c version is used to open the file. Do I need to handle this as a special case? It is possible that there could be " as well, parenthesis, etc.

Should I expect there to be a problem with this as it is written, or is something else going on? I can post the code and test files if that would help.
