    63 It's possible to override exit() by supplying abort(), exit() and _exit()
       
    64 The generic exit() and abort() routines look like
       
    65 
       
    66 void exit(int code) _ATTRIBUTE((noreturn))
       
    67 {

    69  	_exit(code);

    71 void abort(void) _ATTRIBUTE((noreturn))
       
    72 {
       
    73 	_exit(1);
       
    74 }
       
    75 
       
    76 which then allows your _exit() to capture all exits from ESTLIB, 
       
    77 except for __assert() which calls abort().
