ctype and functions that return a pointer to a structure
Hi,
I have the following code:
**
from ctypes import *
g_lib = cdll.LoadLibrary("libc.so.6")
class Struct_Password(Structure):
"""
"""
_fields_ = [ ('name', c_char_p),
('code', c_char_p),
('date', c_long),
('min', c_long),
('max', c_long),
('warn', c_long),
('inact', c_long),
('expire', c_long),
('flag', c_ulong)
]
l_res = g_lib.getspnam('john')
l_struct = cast(l_res, POINTER( Struct_Password() ) )
print l_struct
**
The exception I get is "unhashable type" - apparently cast only handles
simple types.
Is there a way to convert l_res to Struct_Password ?

Python app as a Display Manager
Hi, I asked that question a while back ... and then gave up: I want to write a simple display manager (*nix / X11) in Python. I'm going through lots of documentation as well as the code of XDM. 1) I currently understand that the "X11 Intrinsics" are what I need to master in order to get there. 2) Also, it seems that The Python app needs to adjust to X11 callbacks ... although I will use TKinter or another Framework to actually do the drawing. I feel at this stage that what I miss is: assuming I manage to get a python-based dialog box started automatically from init.rc (instead of xdm, gdm, ...): how do I start an X11 session with the user/pw information retrieved ... + set the correct *nix environment variables.

Is there a technic to avoid this bug
Hi,
In C/C++ I got used to write an expression like so:
#define TEST 0
if (TEST == value)
{
}
in order to avoid the usual bug:
if (value = TEST)
{
}
In a relatively similar domain, I spent a few hours find this bug:
value == self.Get_Value()
if value == WHATEVER:
do this
instead of
value = self.Get_Value()
if value == WHATEVER:
do this
Is there a way to avoid such a bug with some type of construct ?
Thanks,
hg
