I tried to compile the bind.c code. It seems Linux is missing something.
The Linux man page for sched_getaffinity and sched_setaffinity says they
take an unsigned long *. 

int sched_getaffinity(pid_t pid, unsigned int len, unsigned long *mask)

However, the header file says it takes a cpu_set_t pointer.
g++ throws an error that it can't convert from unsigned long* to
cpu_set_t pointer.

In the bind.c code, I changed the mask to type cpu_set_t and it
compiles, but it doesn't run.

./bind 13455 1
pid 13455's old affinity: 00000001
sched_setaffinity: Invalid argument
Exit 255


Anyone else get this to work?
