You could change that to,
Code:
char  str[]="Tanvir/home/root/hello";

Thanks

Dear Nagarajan,

Thanks for ur detailed explaination of strtok.
I fully agree with ur comment.Smilie

they say in such case its safe to use strtok_r().

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 functions write the (null-terminated) character string str on the given window. It is similar to calling waddch once for each char- acter in the string. The mv functions perform cursor movement once, before writing any characters. Thereafter, the cursor is advanced as a side-effect of writ- ing to the window. The four functions with n as the last argument write at most n characters, or until a terminating null is reached. If n is -1, then the entire string will be added. RETURN VALUE
All functions return the integer ERR upon failure and OK on success. X/Open does not define any error conditions. This implementation returns an error o if the window pointer is null or o if the string pointer is null or o if the corresponding calls to waddch return an error. Functions with a "mv" prefix first perform a cursor movement using wmove, and return an error if the position is outside the window, or if the window pointer is null. NOTES
All of these functions except waddnstr may be macros. PORTABILITY
These functions are described in the XSI Curses standard, Issue 4. SEE ALSO
curses(3X), curs_addch(3X). curs_addstr(3X)
