i need to get information about the processes running on a windows pc
(98, 2k, xp)
i can get the pid's using, win32process.EnumProcesses()...and I can get
a handle on a process using an id..such as
handle = win32api.OpenProcess(win32con.PROCESS_QUERY_INFORMATION, 0,
pids[0])
..but how can i get
lt;
}
Is PyResult going to be de-referenced or handled automaticlly by python
in some way? Or, do I need to somehow call Py_DECREF(pyResult)
somewhere..if so, where/when?
Thanks!

I have been posting lately about writing a C wrapper so Python can
access my C functions.
In my wrapper function I have something like...
static PyObject *wrap_doStuff(PyObject *self, PyObject *args) {
PyObject *data;
char *result;
long *d;
PyArg_ParseTuple(args, "O:wrap_doStuff"
I got it. I had get_long_array placed after the method that was
calling it..
i.e.
void doStuf(...) {
x = get_long_array(...);
}
static long *get_long_array(PyObject *data, int *data_size) {
...
}
...I put get_long_array before it in my code..and its fine.
Thanks

Fredrik,

Fredrik...I forgot about that...wish Google Groups had a way to quickly

anyhow, for receiving an object from python..is it

...is it "sO" or "s0" is it O (as in the letter) or 0 (as in the
number)? I would think "O" the

I understand that I can pass a tuple to a C wrapper function and in the
C wrapper function have..
int ok = PyArg_ParseTuple(args, "s(ll)", &a, &b, &c);
..that's great if my tuple only contained two longs..but what if it
contained 50

thanks for the tip, however even when I do not free aString or bString,
i'm still crashing at the malloc in the c function, not the wrapper.

Sorry about the double post...
anyhow, after putting in debug statements I found that it was crashing
when it called, free(result)so I removed the free(result).
now it crashes when it gets to, b = GetVal(bString, count(bString,
","));
..any ideas?

one more update...
if I remove PyMem_Free and free(...) ...so no memory clean up...I can
still only call doStuff 4 times, the 5th attemp crashes Python.

update:
if I use C's free(result), free(a) free(b) instead of PyMem_Free...I
only get one successfuly use/call of doStuff.
i.e.
// this works
doStuff(...)
// python crashes here
doStuff(...)

Hi,

so good. At least for the "simple" functions that I need to wrap.
Ok, my c function looks like...

quick question...how about returning an array of longs? ..or in my
case I have a pointer to an array of longs.

Diez, yes you were right! But I have other problems now.
I now have...

int doStuff(const char *input, const char *d) {...}
static PyObject *wrap_doStuff(PyObject *self, PyObject *args) {

I am having trouble with a wrapper function...
My C code looks like

PyObject *wrap_doStuff(PyObject *, PyObject *args) {

would they go?

I need to write an extension for a C function so that I can call it
from python.
C code (myapp.c)
==
typedef unsigned long MY_LONG;
char *DoStuff(char *input, MY_LONG *x) { ... }
so you pass in a string and an array of MY_LONGS...such as
MY_LONGS vals[10] = {};
char *input = "this is my
I am using SWIG to wrap a C application for use in Python.
C code

// MY_DIGIT is a typedef such as, typedef unsigned long MY_DIGIT;

..I build a DLL named, _MyApp.dll
SWIG interface
(reposting, i was just told how I should properly reply via
groups.google.com)
im sorry, why would it be md_ptr? what is md_ptr?
i tried..
%include cpointer.i
%pointer_functions(MY_DIGIT, digit_ptr)
ptr = new_digit_ptr()
doIt("a message", ptr)
...doesnt work..still needs a DIGIT **

I've tried sending a email to the swig mailing list 3 times...but it
never seems to get it...not sure what is going on, still looking into
it. Until then...
I now have a C function such as...
int doIt(char *a, MY_DIGIT **digit) {
...
}
so I am trying to figure out how to pass in that "digit"
i dont have a myapp.pyd ...i have myapp.c, or are u suggesting I dump
the dll? or the swig generated python file?
the swig generated python file only has .py and .pyc.

do it?
for example i can't do...
>> x = 10944800e
..since it says "invalid token" on the "e".
