Actually, OpenBSD already has this (in the kernel !) After a kernel crash ones, I got in the kerneldebugger. I didn't really know how to use it, but I could play hangman. I just downloaded the source (pub/OpenBSD/2.7/srcsys.tar.gz) to be sure, here is a short excerpt from sys/ddb/db_hangman.c: --- static __inline char * db_randomsym(lenp) size_t *lenp; { register char *p, *q; /* choose random symtab */ register db_symtab_t stab = db_istab(db_random(db_nsymtabs));
/* choose random symbol from the table */ q = db_qualify(X_db_isym(stab, db_random(X_db_nsyms(stab))),stab->name);
/* don't show symtab name if there are less than 3 of 'em */ if (db_nsymtabs < 3) while(*q++ != ':');
/* strlen(q) && ignoring underscores and colons */ for ((*lenp) = 0, p = q; *p; p++) if (ISALPHA(*p)) (*lenp)++;
return q; }
static char hangpic[]= "\n88888 \r\n" "9 7 6 \r\n" "97 5 \r\n" "9 423\r\n" "9 2 \r\n" "9 1 0\r\n" "9\r\n" "9 "; static char substchar[]="\\/|\\/O|/-|";
--- and an other part: ---
void db_hangman(addr, haddr, count, modif) db_expr_t addr; int haddr; db_expr_t count; char *modif; { if (modif[0] == 's' && '0' <= modif[1] && modif[1] <= '9') skill = modif[1] - '0'; else skill = 5;
while (db_hangon()); }
