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.

InflateInputStreambuf()

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.
