zlib::deflate_stream::reset (1 of 2 overloads)

Reset the stream and compression settings.

Synopsis

void
reset(
    int level,
    int windowBits,
    int memLevel,
    Strategy strategy);

Description

This function initializes the stream to the specified compression settings. Although the stream is ready to be used immediately after a reset, any required internal buffers are not dynamically allocated until needed.

Parameters

Name	Description
`level`	Compression level from 0 to 9.
`windowBits`	The base two logarithm of the window size, or the history buffer. It should be in the range 9..15.
`memLevel`	How much memory should be allocated for the internal compression state, with level from from 1 to 9.
`strategy`	Strategy to tune the compression algorithm.

Remarks

Any unprocessed input or pending output from previous calls are discarded.
