Speaking for Unix, a daemon program is not very special.

It has normally the following features:

- It runs in the background, without attached terminal (standard
input). That is in C usually achieved by closing the standard input
and doing a fork() (or vice versa?). This is almost equivalent to
creating a new thread, so the threads interface should be enough.

- It sometimes reacts specially to interrupts, for example it may
read-read its configuration file if it receives a SIGHUP

- It uses frequently protected services and ports and thus runs with
root or other special privileges.

- An advanced daemon may send log messages to the syslog daemon, which
will write it to a file as /var/log/messages, or send it to another

- It starts normally automatically by a call from the system startup

As can be seen, this should be achieved easily with standard commands,
except perhaps the interrupt protection.
