The Robot
Beginning with gawk 3.1, it is possible to add new built-in
functions to gawk using dynamically loaded libraries. This
facility is available on systems (such as GNU/Linux) that support
the dlopen and dlsym functions.
This section describes how to write and use dynamically
loaded extensions for gawk.
Experience with programming in
C or C++ is necessary when reading this section.
Caution: The facilities described in this section are very much subject to change in a future gawk release. Be aware that you may have to re-do everything, perhaps from scratch, at some future time.
