zapette emulate a file that is remotely controlled by slave_zapette
class zapette sends order to slave_zapette throw a a first pipe and receive informations or data in return from a second pipe from slave_zapette
libdar::zapette::zapette | ( | user_interaction & | dialog, |
generic_file * | input, | ||

zapette constructor
[in] | dialog | is used to return status information to the user |
[in] | input | is the pipe (see class tuyau) from which is received the information or data |
[in] | output | is used to send orders to slave_zapette |

implementation of read() operation
[in,out] | a | where to put the data to read |
[in] | size | says how much data to read |
Implements libdar::generic_file.
void libdar::zapette::inherited_sync_write | ( | ) | [inline, protected, virtual] |
write down any pending data
Implements libdar::generic_file.
