Hi thanks for your response in the last piece of c code i want to know how do i pass structure into python function in c. I have tried to call a python function which takes string as parameter.
i have passed string parameter as : const char *str_pArgs = "hello"; pArgs = PyTuple_New(1); pValue = PyString_FromString(str_pArgs); PyTuple_SetItem(pArgs, 0,pValue); pValue = PyObject_CallObject(pFunc, pArgs); similarly how do i convert this structure for python function argument. ->pArgs = e //******************logic to assign struct employee into pArgs regards ah On Tue, Jan 12, 2010 at 5:33 PM, a h <ah.k...@gmail.com> wrote: > Hi > I have witten C code which call a function defined in python, passing an > structure, but couldn't know how to pass c structure into a python > function(data conversion) and how to write python script function which > takes an c structure and fill value into it (commented portion) > > I have looked at struct module but couldn't understand that how it works > for below. > > typedef struct employee > { > char emp_name[10]; > int emp_ID; > }emp; > > int main() > { > emp e = {0}; > Pyobject *pName, *pModule, *pFunc, *pArgs,*pValue; > Py_Initialize(); > pName = PyString_FromString("test"); > pModule = PyImport_Import(pName); > Py_DECREF(pName); > if (pModule != NULL) > { > pFunc = PyObject_GetAttrString(pModule, "testStruct"); > if(pFunc && PyCallable_Check(pFunc)) > { > pArgs = e //******************logic to assign struct employee into pArgs > pValue = PyObject_CallObject(pFunc, pArgs); > } > } > Py_DECREF(pValue); > Py_DECREF(pModule); > Py_Finalize(); > return 0; > } > > and now python script test.py > def testStruct(): # **** need any parameter will be specify > #**** assign value into the cStructure > f=open(filename) > f.write(cStructure.Value) # **** value to write in file > > Thanks in advance > regards > ah >
