A simple example
Suppose we have the following C API to expose to Python:
#include
Namespace {// Avoid Cluttering The Global Namespace.
// a Couple of Simple C Functions That We want to express to python.
Std: string greet () {return "hello, world";
INT Square (int Number) {Return Number * Number;}
}
This is to expose the C source code for the API Getting_Started1 module to Python.
#include
Namespace python = boost :: python;
BOOST_PYTHON_MODULE_INIT (Getting_Started1)
{
Try
{
// Create An Object Representing this Extension Module.
Python :: Module_builder this_module ("getting_started1");
// Add regular functions to the module.
This_Module.def (Greet, "Greet");
this_module.def (Square, "Square");
}
Catch (...)
{
Python :: handle_exception (); // deal with the exception for python
}
}
It is! If we generate this shared library and put it in Python's search path, we can access these C functions in Python.
>>> Import getting_started1
>>> Print getting_started1.greet ()
Hello, World
>>> NUMBER = 11
>>> Print Number, '*', Number, '=', getting_started1.square (Number)
11 * 11 = 121
