|

|
* DESCRIPTION
|
||
|
*
|
||
|
* Append_archive reads an archive until the end of the archive is
|
||
|
* reached once the archive is reached, the buffers are reset and the
|
||
|
* create_archive function is called to handle the actual writing of
|
||
|
* the appended archive data. This is quite similar to the
|
||
|
* read_archive function, however, it does not do all the processing.
