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 extentions 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 the next gawk release.
Be aware that you may have to re-do everything, perhaps from scratch,
upon the next release.
