gawk: Dynamic Extensions

 
 16 Writing Extensions for 'gawk'
 ********************************
 
 It is possible to add new functions written in C or C++ to 'gawk' using
 dynamically loaded libraries.  This facility is available on systems
 that support the C 'dlopen()' and 'dlsym()' functions.  This major node
 describes how to create extensions using code written in C or C++.
 
    If you don't know anything about C programming, you can safely skip
 this major node, although you may wish to review the documentation on
 the extensions that come with 'gawk' (Extension Samples), and
 the information on the 'gawkextlib' project (gawkextlib).  The
 sample extensions are automatically built and installed when 'gawk' is.
 
      NOTE: When '--sandbox' is specified, extensions are disabled (
      Options).
