@class wxZipInputStream
Input stream for reading zip files.
wxZipInputStream::GetNextEntry returns an
wxZipEntry object containing the meta-data
for the next entry in the zip (and gives away ownership). Reading from
the wxZipInputStream then returns the entry's data. Eof() becomes @true
after an attempt has been made to read past the end of the entry's data.
wxZipInputStream::GetNextEntry() returns a wxZipEntry object containing the
meta-data for the next entry in the zip (and gives away ownership).
Reading from the wxZipInputStream then returns the entry's data.
Eof() becomes @true after an attempt has been made to read past the end of
the entry's data.
When there are no more entries, GetNextEntry() returns @NULL and sets Eof().
Note that in general zip entries are not seekable, and
wxZipInputStream::SeekI() always returns wxInvalidOffset.
wxZipInputStream::SeekI() always returns ::wxInvalidOffset.
