NAME
Filter::Util::Exec - exec source filter
SYNOPSIS
use Filter::Util::Exec;
DESCRIPTION
This module is provides the interface to allow the creation of Source
Filters which use a Unix coprocess.
See Filter::exec, Filter::cpp and Filter::sh for examples of the use of
this module.
Note that the size of the buffers is limited to 32-bit.
filter_add()
The function, "filter_add" installs a filter. It takes one parameter
which should be a reference. The kind of reference used will dictate
which of the two filter types will be used.
If a CODE reference is used then a closure filter will be assumed.
If a CODE reference is not used, a method filter will be assumed. In a
method filter, the reference can be used to store context information.
The reference will be blessed into the package by "filter_add".
See Filter::Util::Call for examples of using context information using
both method filters and closure filters.
