Adding New Built-in Functions to `gawk'
=======================================
Danger Will Robinson! Danger!!
Warning! Warning!
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 minor node describes how to write and use
dynamically loaded extentions for `gawk'. Experience with programming
in C or C++ is necessary when reading this minor node.
*Caution:* The facilities described in this minor node 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.
