Looking at this code
Code:
 f12=fopen(proc_status,"r");fseek(f12,20,SEEK_SET);str=fgetc(f12);
    if(str!='Z'){shoot++;kill(pid,9);}

I assume that your problem is that the SIGKILL is being triggered irrespective of whether the character at offset 20 is "Z' or not.

Is 'str' declared as a char or an int?

Also note that if fopen(), fseek() or fgetc() fail the if statement will still be executed with str probably set to some unknown/random value and hence SIGKILL will be triggered. You need to add error checking to avoid this scenario.

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 entire string will be added. 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. 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)
