Struct devela::all::LINUX_SIGNAL

source · 
pub struct LINUX_SIGNAL;
Available on crate feature linux only.
Expand description

Linux standard signals constants.

Each signal has a current disposition, which determines how the process behaves when it is delivered the signal.

  • Term: Default action is to terminate the process.
  • Ign: Default action is to ignore the signal.
  • Core: Default action is to terminate the process and dump core (see core(5)).
  • Stop: Default action is to stop the process.
  • Cont: Default action is to continue the process if it is currently stopped.

The signals SIGKILL and SIGSTOP cannot be caught, blocked, or ignored.
