google "curses getch". Google is your friend.

You need to call iniscr() first to create the default window. getch() is like wgetch() but it assumes the default window, which you haven't initialized. You can't make assumptions with C. It is a low-level language.

Or, in the case you do not really need curses, just do:
Code:

#include <stdio.h>
int main()
{
  int c;
  c = getchar();
}

...
...
initscr();
int i = 0;
while ((inBuf[i++] = getch())!= '\n')
{
printw(" * ");
}
...

It seems that initscr() will clear the whole screen.

I am using getch() only to get password from user(another program will call this getpassword() function),
so there is no need to clear the screen or create a new window to get password.

How to keep all the things on the screen but use getch()?
