.Dt INFLATEBACKINIT 3
.Os
.
.Sh NAME
.Nm inflateBackInit
.Nd initialize inflateBack stream
.
.Sh LIBRARY
.Lb libz
.
.Sh SYNOPSIS
.In zlib.h
.Ft int
.Fo inflateBackInit
.Fa "z_streamp strm"
.Fa "int windowBits"
.Fa "unsigned char FAR *window"
.Fc
.
.Sh DESCRIPTION
Initialize the internal stream state
for decompression using
.Xr inflateBack 3
calls.
The fields
.Fa zalloc ,
.Fa zfree
and
.Fa opaque
in
.Fa strm
must be initialized before the call.
If
.Fa zalloc
and
.Fa zfree
are
.Dv Z_NULL ,
then the default
library-derived memory allocation routines are used.
.Fa windowBits
is the base two logarithm of the window size,
in the range 8..15.
.Fa window
is a caller supplied buffer of that size.
Except for special applications
where it is assured that deflate
was used with small window sizes,
.Fa windowBits
must be 15
and a 32K byte
.Fa window
must be supplied
to be able to decompress general deflate streams.
.
.Sh RETURN VALUES
.Fn inflateBackInit
will return
.Dv Z_OK
on success,
.Dv Z_STREAM_ERROR
if any of the parameters are invalid,
.Dv Z_MEM_ERROR
if the internal state could not be allocated,
or
.Dv Z_VERSION_ERROR
if the version of the library
does not match the version of the header file.
