New submission from David Wood <dwoodjunkm...@gmail.com>:
I have a c function to encrypt values which returns an array of bytes. The
function returns proper values outside of python. When used as a python
function, the result is incomplete usually 10-20% of the time. If I add a
sleep(1) call before returning from the function, my success rate goes to 100%.
While this works, it is unacceptable as it will create enormous latency in my
application.
static PyObject *method_encrypt(PyObject *self, PyObject *args) {
char *keyval, *str = NULL, output[512];
Py_ssize_t count=0;
PyObject *retval;
if(!PyArg_ParseTuple(args, "ss", &str, &keyval)) {
return NULL;
}
encryptBlowfishCfb(str, &count, output, keyval);
retval = Py_BuildValue("y#", output, count);
//sleep(1);
return retval;
}
