Just curious...

I was looking at the bsd ptrace call to port strace to it...

I notice in linux we have:
efine PTRACE_TRACEME 0
#define PTRACE_PEEKTEXT 1
#define PTRACE_PEEKDATA 2
#define PTRACE_PEEKUSR 3
#define PTRACE_POKETEXT 4
#define PTRACE_POKEDATA 5
#define PTRACE_POKEUSR 6
#define PTRACE_CONT 7
#define PTRACE_KILL 8
#define PTRACE_SINGLESTEP 9

#define PTRACE_ATTACH 0x10
#define PTRACE_DETACH 0x11

and bsd has:
#define PT_TRACE_ME 0 /* child declares it's being traced */
#define PT_READ_I 1 /* read word in child's I space */
#define PT_READ_D 2 /* read word in child's D space */
#define PT_READ_U 3 /* read word in child's user structure */
#define PT_WRITE_I 4 /* write word in child's I space */
#define PT_WRITE_D 5 /* write word in child's D space */
#define PT_WRITE_U 6 /* write word in child's user structure */
#define PT_CONTINUE 7 /* continue the child */
#define PT_KILL 8 /* kill the child process */
#define PT_STEP 9 /* single step the child */
#define PT_ATTACH 10 /* trace some running process */
#define PT_DETACH 11

Any reason PT_ATTACH/PT_DETACH are hex instead of decimal?
