gawk: Extension API Description

 
 16.4 API Description
 ====================
 
 C or C++ code for an extension must include the header file 'gawkapi.h',
 which declares the functions and defines the data types used to
 communicate with 'gawk'.  This (rather large) minor node describes the
 API in detail.
