dm_pipe_execute Function

public function dm_pipe_execute(command, output, n) result(rc)

Utility function that reads output from pipe. The output must be at least the length of the expected output + 1, due to the returned null-termination. The null character at the end will be removed.

The function returns the following error codes:

  • E_READ if pipe returned no bytes.
  • E_SYSTEM if system call failed.
