Hello experts,

i have one query which i am not able to solve please suggest me my problem is i have to open a filedescriptor and have to store the contents in streambuffer,

int main () {

 char ch;
 streambuf * pbuf;size_t size;
  ifstream istr(const char *)fd);
  pbuf = istr.rdbuf();

  while (pbuf->sgetc()!=EOF)
     ch = pbuf->sbumpc();
     cout << ch;


  return 0;
but here the line
ifstream istr(const char *)fd);
is not properly interpreting thats why there is no out put

if i simply give
ifstream istr(fd);
it gives me error as this method does not exist,
please helop me what to do but i want the result in <b>streambuffer</b> because this is the input for some other module in my project pleasesuggest what are the different way i can get so the i get the contents in <b>streambuffer.</b>

thanks in advance.
