The sys module has its own set of special functions like
PySys_GetObject. The following (untested) code should take care of error
checking and ref counting.
#include "Python.h"
PyObject*
addtosyspath(const char* addpath) {
PyObject *syspath=NULL, *path=NULL;
int result;
if ((syspath = PySys_GetObject("path")) == NULL)
return NULL;
if ((path = PyString_FromString(addpath) == NULL) {
Py_DECREF(syspath);
return NULL;
}
result = PyList_Insert(syspath, 0, path);
Py_DECREF(syspath);
Py_DECREF(path);
if (result != 0)
return NULL;
Py_RETURN_NONE;
}
