--------------------------------------
Chris,
It was so long ago. I think I was asking for exactly what you showed as an
example.
Maybe my concerns was registering these stats. From a driver perspective, I I
was probably thinking about how to dynamically create these when someone
initialized the driver and then register with the stats module.
STATS_SECT_DECL(my_stats) *ps = malloc(sizeof(STATS_SECT_DECL(my_stats))
stats_register("foo", ps).
So I have to pass a name as a const string since you are not copying it.
But when I do this dynamically, I have to keep that string somewhere.
Like we discussed I could do this
struct my_driver_instance {
char *stat_name[32]
STATS_SECT_DECL(my_stats) *ps
/* my other driver state */
}
And then I could sprint a stats name like
sprintf(myd->name, "mdriver%d", i)
stats_register(myd->name, myd->ps)
So I think that covers it.
> stats module does not allow multiple instances of the same section

> Suppose I make a driver for peripheral X. My driver supports up to 3
> peripherals of type X. I want each one to have a unique name.
> px_1
> px_2
> px_3
> Right now it takes a bit of fussing to do this since the stats modules does
> not copy the name.
