Top Forums Programming How to find if a process a daemon ? Post 302218705 by matrixmadhan on Saturday 26th of July 2008 03:06:01 AM

Code:
Can a daemon process have a ppid other than 1 ?

Any process guarded from SIGHUP signal as nohup process and detached from controlling terminal will have a ppid of 1, but they are not daemonized.

How about this - to check for the masking permissions ? I know its not a standard practice that needs to be followed before daemonizing a process but its more of a practice.
