Module Low_level.ProcessSource

A child process.

Setup actions to perform in the child process.

spawn ~sw actions forks a child process, which executes actions. The last action should be Fork_action.execve.

You will typically want to do Promise.await (exit_status child) after this.

• parameter sw

  The child will be sent Sys.sigkill if sw finishes.

signal t x sends signal x to t.

This is similar to doing Unix.kill t.pid x, except that it ensures no signal is sent after t has been reaped.

exit_status t is a promise for the process's exit status.
