An external output function is a function to which a stream item can be attached. Such a stream is called an external output stream. Any data written to the stream item is processed by the function.
External output functions are defined using the define external output declaration.
The set action can be used directly on external output functions in the same way that it can be used on files and referents.
For example, the following illustrates using the set action directly on external output functions.
define external output function http-connection
(value stream requesting-id) as "http_con"
in function-library "http.dll"
...
find ...
local stream requesting-id
local stream requested-file-name
...
set http-connection (requesting-id) to
file (requested-file-name)
More information about external output functions is available in the OmniMark external function programmer's guide .
