how to get string printed by PyErr_Print( )?

[grbgooglefan]

PythonC API function PyErr_Print( ) prints an error string onto stderr
if PyErr_Occurred() is true.
I don't want to print this to stderr because my Python+C code is
running daemon mode & won't have terminal / stderr.
So, I want to retrieve the string which PyErr_Print( ) will print.
E.g., PyErr_Print() printed following string when I tried to call
setTuple with one extra argument
Traceback (most recent call last):
  File "<string>", line 2, in isTacticSafe
IndexError: tuple assignment index out of range

How do I get this error message in a local char* & use it for further
error handling?

Also, is there any way to get an error number associated for these
error conditions using some getError function on the object returned
by PyErr_Occurred()?

Thanks.
