Hi
I am writing some C code which sets and retrieves a Python exception. I
set the exception using PyErr_SetString(), and retrieve it in 2 ways: 1)
using PyErr_Occurred() and 2) Using sys.exc_type. However, I get two
different results and am very puzzled by this apparent inconsistency.
Could anyone please clarify what I'm missing? I need both to work
consistently for my application.
Here is the C code and the output
#include "Python.h"
#define OPRINT(o) PyObject_Print((o),stdout,0);printf("\n")
int main() {
PyObject *sysmod,*etype1,*etype2;
Py_Initialize();
sysmod = PyImport_ImportModule("sys");
PyErr_SetString(PyExc_Exception,"HI"); //set exception
etype1 = PyObject_GetAttrString(sysmod,"exc_type"); //sys.exc_type
etype2 = PyErr_Occurred();
printf("sys.exc_type : "); OPRINT(etype1);
printf("PyErr_Occurred() : "); OPRINT(etype2);
}
The output
sys.exc_type : None
PyErr_Occurred() : <type 'exceptions.Exception'>
Thank you
Raj
