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.
