libdar_slave constructor

Parameters

  [in] | dialog | for user interaction. Can be set to nullptr
  [in] | folder | is the directory where resides the backup to read
  [in] | basename | is the backup basename
  [in] | extension | should be set to "dar"
  [in] | input_pipe_is_fd | if true the input_pipe argument is expected to be an integer (a file descriptor open for reading)
  [in] | input_pipe | is the name of the pipe order will come from or a filedescriptor if input_pipe_is_fd is true
  [in] | output_pipe_is_fd | if true the output_pipe argument is expected to be an integer (a file descriptor open for writing)
  [in] | output_pipe | is the name of the pipe to send data to dar or a filedescriptor depending on output_pipe_is_fd value
  [in] | execute | is a command to execute before reading a new slice, same macro substition is available as libdar::archive::set_execute()
  [in] | min_digits | minimum digits used to create the archive. Set it to zero if this option was not used at archive creation time

Note
  if input_pipe is an empty string stdin is used
  if output_pipe is an empty string stdout is used

## ◆ run()

void libdar::libdar_slave::run | ( |  | ) |

enslave this object to the dar process through the created pipes

Note
  run() will return when dar will no more need of this slave. if you need to abort this run(), let dar abort properly this will do the expected result properly.
