 **InflateInputStreambuf** *constructor.*  bool **reset** (int stream\_position=-1)\
 *Resets the zlib stream and purges input and output buffers.*

## 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.

## Constructor & Destructor Documentation

### zipios::InflateInputStreambuf::InflateInputStreambuf (streambuf \* inbuf, int s\_pos = `-1`, 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.

Definition at line 18 of file inflateinputstreambuf.cpp.

## 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.
