Re: how to pass vector<char> as parameter?

I am working on a file parser.

void process_file(std::string filename)
{
 //FILE *afile;
 char c;

 ifstream infile(filename.c_str ());

 //if ((afile = fopen (filename, "rt")) == NULL)
 //{
 // exit(0);
 //}
 if(!infile)
 {
  cerr<<"Can't open file " << filename << endl;
  exit(-1);
 }

 //fileData = (char *) malloc (50000);
// memset (fileData, 0, sizeof(fileData));
// fread (fileData, sizeof(char), sizeof(fileData), afile);
 while (infile >> c)
 {
  fileData.push_back(c);
 }

 printf ("Parsing %s\n", filename.c_str());
    parse (fileData, fileData.size());
}

void parse (vector<char> buf, long count)
{
 int i,j;
 char *tokens[256];
 long cnt = 0; // count for number of tokens
 char c;
 bool ignore = false;
 int k = 0;

 char buff[256];
 PCSTR buf2 = &buf[0];
// char p;
 std::string buf3;
// static long token_count = 0;

 for (;;) {
  memset (buff, 0, 256);
  trim (buf2);
  is_comment(buf2[0], buf2[1]);
  if (one_line_comment)
  {
   while (*buf2 != '\n') <<<<<<<<<<<< when I took a view at buf2, all \n
disappeared
    buf2++;
   buf2++; // Skip tail \n
