I am trying some simple c API, where I am using PyCapsule_New to encapsulate a pointer. I am running into segment violation, can some body help me.

mystruct *func1(int streamno, char mode,unsigned int options) { char * s; s=malloc(100); return s; }

PyObject *Wrapper_func1(PyObject *self, PyObject *args)
{
    int streamno;
    char mode;
    unsigned int options;    
    mystruct* result;
    if (!PyArg_ParseTuple(args,"icI",&streamno,&mode,&options))
      return NULL;
    result = func1(streamno,mode,options);
    return PyCapsule_New( result,NULL,NULL);
}
