Dynamically loading a shared library

If you want to programmatically control the loading and initialization of C++ objects contained in shared libraries, you can use two functions provided by XL C/C++: loadAndInit and terminateAndUnload. These functions are declared in the header file load.h, and you can call them from the main program to load, initialize, terminate, and unload any named shared library. These functions work in the same way, take the same parameters, and return the same values and error codes as the AIX® load and unload routines, respectively, but they additionally perform initialization of C++ objects. See the load and unload routines in the Technical Reference: Base Operating System and Extensions, Volumes 1 & 2 for more information.
Note: For portability, you might wish to use the POSIX dlopen and dlclose functions, which also perform initialization and termination, and interact correctly with loadAndInit and terminateAndUnload. For more information on dlopen and dlclose, see the Technical Reference: Base Operating System and Extensions, Volumes 1 & 2.
