Parent pid or parent process of a process

Description

ps_ppid() returns the parent pid, ps_parent() returns a ps_handle of the parent.

Usage

ps_ppid(p)

ps_parent(p)

Arguments

Details

On POSIX systems, if the parent process terminates, another process (typically the pid 1 process) is marked as parent. ps_ppid() and ps_parent() will return this process then.

Both ps_ppid() and ps_parent() work for zombie processes.

Value

ps_ppid() returns and integer scalar, the pid of the parent of p. ps_parent() returns a ps_handle.

Examples

p <- ps_handle()
p
ps_ppid(p)
ps_parent(p)
