* DESCRIPTION
|
|
|
55 |
*
|
|
|
56 |
* Append_archive reads an archive until the end of the archive is
|
|
|
57 |
* reached once the archive is reached, the buffers are reset and the
|
|
|
58 |
* create_archive function is called to handle the actual writing of
|
|
|
59 |
* the appended archive data. This is quite similar to the
|
|
|
60 |
* read_archive function, however, it does not do all the processing.
