Constructor & Destructor Documentation

libdar_slave()

libdar::libdar_slave::libdar_slave	(	std::shared_ptr< user_interaction > &	dialog,
		const std::string &	folder,
		const std::string &	basename,
		const std::string &	extension,
		bool	input_pipe_is_fd,
		const std::string &	input_pipe,

	)

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

Member Function Documentation

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.
