Detailed Description
InflateInputStreambuf is an input stream filter, that inflates the input from the attached input stream.
Deflation/Inflation is a compression/decompression method used in gzip and zip. The zlib library is used to perform the actual inflation, this class only wraps the functionality in an input stream filter.

| bool | del_inbuf = false | |||
| ) | [explicit] |
InflateInputStreambuf constructor.
- Parameters:
-
inbuf the streambuf to use for input. s_pos a position to reset the inbuf to before reading. Specify -1 to read from the current position. del_inbuf if true is specified inbuf will be deleted, when the InflateInputStreambuf is destructed.

Member Function Documentation
| bool zipios::InflateInputStreambuf::reset | ( | int | stream_position = -1 |

Resets the zlib stream and purges input and output buffers.
repositions the input streambuf at stream_position.
- Parameters:
-
stream_position a position to reset the inbuf to before reading. Specify -1 to read from the current position.
