[Bluez-devel] hciattach <--> hcid

[Choi Sonim]

hello all,

when I do hciattach, i see that hcid automatically add the new device,
and when i send -SIGTERM to hciattach, i see that hcid removed the device.

how does hcid knows about all these changes ?
where is the communication ?

thank you all
choi

the kernel will tell hcid when a new host adapter has been attached or
removed from the system.
