The following C source file (which we will call hello.c for demonstration purposes) produces an extension module named hello that contains a single function greet():
#include <Python.h>
#include <stdio.h>
#if PY_MAJOR_VERSION >= 3
#define IS_PY3K
#endif
static PyObject *hell...
Pass an open file object from Python to C extension code.
You can convert the file to an integer file descriptor using PyObject_AsFileDescriptor function:
PyObject *fobj;
int fd = PyObject_AsFileDescriptor(fobj);
if (fd < 0){
return NULL;
}
To convert an integer file descriptor back ...
This is a basic example of a C Extension using C++ and Boost.
C++ Code
C++ code put in hello.cpp:
#include <boost/python/module.hpp>
#include <boost/python/list.hpp>
#include <boost/python/class.hpp>
#include <boost/python/def.hpp>
// Return a hello world string.
