.Dt DEFLATEPRIME 3
.Os
.
.Sh NAME
.Nm deflatePrime
.Nd insert bits in deflate stream
.
.Sh LIBRARY
.Lb libz
.
.Sh SYNOPSIS
.In zlib.h
.Ft int
.Fn deflatePrime "z_streamp strm" "int bits" "int value"
.
.Sh DESCRIPTION
.Fn deflatePrime
inserts bits in the deflate output stream.
The intent is that this function
is used to start off the deflate output
with the bits leftover
from a previous deflate stream
when appending to it.
As such,
this function can only be used for raw deflate,
and must be used before the first
.Xr deflate 3
call
after a
.Xr deflateInit2 3
or
.Xr deflateReset 3 .
.Fa bits
must be less than or equal to 16,
and that many of the least significant bits of
.Fa value
will be inserted in the output.
.
.Sh RETURN VALUES
.Fn deflatePrime
returns
.Dv Z_OK
if success,
.Dv Z_BUF_ERROR
if there was not enough room
in the internal buffer
to insert the bits,
or
.Dv Z_STREAM_ERROR
if the source stream state was inconsistent.
