DESCRIPTION

12       This module is provides the interface to allow the creation of Source
13       Filters which use a Unix coprocess.
14
15       See Filter::exec, Filter::cpp and Filter::sh for examples of the use of
16       this module.
17
18       Note that the size of the buffers is limited to 32-bit.
19
20   filter_add()
21       The function, "filter_add" installs a filter. It takes one parameter
22       which should be a reference. The kind of reference used will dictate
23       which of the two filter types will be used.
24
25       If a CODE reference is used then a closure filter will be assumed.
26
27       If a CODE reference is not used, a method filter will be assumed.  In a
28       method filter, the reference can be used to store context information.
29       The reference will be blessed into the package by "filter_add".
30
31       See Filter::Util::Call for examples of using context information using
32       both method filters and closure filters.
