Libsf is a stack fingerprinting library that allows the following:

libsf_t *s;                                                                     
                                                                                
s = libsf_init(LIBSF_ACTIVE, device, argv[optind], 0, 1, flags, errbuf);        
libsf_active_id(s);                                                             
                                                                                
/* get the total number of matches */                                           
tm = libsf_os_get_tm(s);                                                        
                                                                                
/* get the high score */                                                        
hs = libsf_os_get_hs(s);                                                        
                                                                                
printf("%d potential matches (highest score of %d)\n", tm, hs);                 
printf("Highest scored OS guesses:\n");                                         
                                                                                
/* run through the OS list, dumping string that matches score */                
while ((guess = libsf_os_get_match(s, hs)))                                     
{                                                                               
        printf("%s\n", guess);                                                  
}                                                                               
                                                                                
libsf_destroy(s);
