C语言调用Python函数（二）

C语言调用Python函数的主要框架比较简单，当然还有些具体细节没涉及：

PyObject *pModule;
PyObject *pFunction;
PyObject *pArgs;
PyObject *pRetValue;

Py_Initialize();
if ( !Py_IsInitialized())
    return -1;
pModule = PyImport_ImportModule("PyTest") ;//PyTest就是PyTest.py,不要后缀名
pFunction = PyObject_GetAttrString(pModule, FunctionName); //FunctionName是PyTest脚本中要调用的函数名
pArgs = PyTuple_New(2); //2个参数
PyTuple_SetItem(pArgs, 0, Py_BuildValue("l", 5));
PyTuple_SetItem(pArgs, 1, Py_BuildValue("l", 7));

pRetValue = PyObject_CallObject(pFunction, pArgs);

printf("ret=%d\n", PyInt_AsLong(pRetValue));
printf("ret=%s\n", PyString_AsString(pRetValue));
