+.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.
+.
