.Sh DESCRIPTION
|
|
The
|
|
.Fn xo_set_writer
|
|
function allows custom
|
|
.Dq write
|
|
functions
|
|
which can tailor how
|
|
.Nm libxo
|
|
writes data.
|
|
An
|
|
.Fa opaque
|
|
argument is
|
|
recorded and passed back to the
|
|
.Fa write_func
|
|
function, allowing the function
|
|
to acquire context information.
|
|
The
|
|
.Fa close_func
|
|
function can
|
|
release this opaque data and any other resources as needed.
|
|
The
|
|
.Fa flush_func
|
|
function should
|
|
flush any pending data associated with the opaque pointer.
