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.

| 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.
