1. addch prints undesired character

Hi,
   I am writing a program on HP-UX that has to accept a password. The
password string should be displayed as ***.. on the screen. I am using
noecho() function of curses library to set echo to off. For each
character that I receive from the user I display a '*' by using
addch('*). My piece of code roughly looks like this
void main() {
   //1
   initscr();

   //2
   noecho();

   //3
   Call a function that does some data base operation through proc code

   //4
   Get characters from the user
   //5
   addch('*'); //for each character

If the user enters password as secret. Instead of displaying ****** on
the screen, I get P*****. I don't know why this P is getting printed.
If I comment out the function that makes proc calls, then the display
part works fine. But with the proc code I always get some vague

Will anybody help me?

Thanks in advance
