Detailed Description

SQLAPI++ C interface functions.

SQLAPI++ C interface functions are built on C++ classes and methods. They are compiled by C++ compiler but can be used in pure C code - just include the same SQLAPI.h header file in your sources, compile and link them with SQLAPI++ library.

SQLAPI++ C functions interact with C++ interfaces by using 'handles' - pointers to SQLAPI++ objects that are declared as structs for C code.
