.Sh LIBRARY

.Sh SYNOPSIS
.In zlib.h
.Ft int
.Fn inflateReset "z_streamp strm"
.Ft int
.Fn inflateReset2 "z_streamp strm" "int windowBits"
.
.Sh DESCRIPTION
This function is equivalent to
.Xr inflateEnd 3
followed by
.Xr inflateInit 3 ,
but does not free and reallocate
the internal decompression state.
The stream will keep attributes
that may have been set by
.Xr inflateInit2 3 .
.
.Pp
.Fn inflateReset2
is the same as
.Fn inflateReset ,
but it also permits changing
the wrap and window size requests.
The
.Fa windowBits
parameter is interpreted the same as it is for
.Xr inflateInit2 3 .
If the window size is changed,
then the memory allocated for the window is freed,
and the window will be reallocated by
.Xr inflate 3
if needed.
.
.Sh RETURN VALUES
.Fn inflateReset
and
.Fn inflateReset2
return
.Dv Z_OK
if success,
or
.Dv Z_STREAM_ERROR
if the source stream state was inconsistent
.Po
such as
.Fa zalloc
or
.Fa state
being
.Dv Z_NULL
.Pc ,
or if the
.Fa windowBits
parameter is invalid.
