Pointers don't work that way. "str" is just an integer that points to memory local to a process, it won't be meaningful to whoever recieves it.

s1 has to be a pointer, since that is what malloc returns. But unless you need it to be persistent, you may not need to allocate it.

You can't declare a struct variable like "samp s1", you have to say "struct samp s1".

Try it like this:

Code:
struct {
  int i;
  char str[16];
}samp;

...

struct samp s1;

s1.i=1234;
strcpy(s1.str,"Data");

...

curs_addstr(3X) 														   curs_addstr(3X)

NAME
addstr, addnstr, waddstr, waddnstr, mvaddstr, mvaddnstr, mvwaddstr, mvwaddnstr - add a string of characters to a curses window and advance cursor SYNOPSIS
#include <curses.h> int addstr(const char *str); int addnstr(const char *str, int n); int waddstr(WINDOW *win, const char *str); int waddnstr(WINDOW *win, const char *str, int n); int mvaddstr(int y, int x, const char *str); int mvaddnstr(int y, int x, const char *str, int n); int mvwaddstr(WINDOW *win, int y, int x, const char *str); int mvwaddnstr(WINDOW *win, int y, int x, const char *str, int n); DESCRIPTION
These routines write the characters of the (null-terminated) character string str on the given window. It is similar to calling waddch once for each character in the string. The four routines with n as the last argument write at most n characters. If n is -1, then the en- tire string will be added, up to the maximum number of characters that will fit on the line, or until a terminating null is reached. RETURN VALUE
All routines return the integer ERR upon failure and OK on success (the SVr4 manuals specify only "an integer value other than ERR") upon successful completion. X/Open does not define any error conditions. This implementation returns an error if the window pointer is null or if the string pointer is null or if the corresponding calls to waddch return an error. NOTES
Note that all of these routines except waddstr and waddnstr may be macros. PORTABILITY
All these entry points are described in the XSI Curses standard, Issue 4. The XSI errors EILSEQ and EOVERFLOW, associated with extended- level conformance, are not yet detected. SEE ALSO
curses(3X), curs_addch(3X). curs_addstr(3X)
