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" pointer.
My SWIG interface file looks like...
extern int doIt(char *a, MY_DIGIT **digit);
%include cpointer.i
%pointer_functions(MY_DIGIT, md_prt);
%typemap(in) (char *a, MY_DIGIT **argv) {
/* Check if is a list */
if (PyList_Check($input)) {
int i;
$1 = PyList_Size($input);
$2 = (MY_DIGIT **) malloc(($1+1)*sizeof(long *));
for (i = 0; i < $1; i++) {
PyObject *o = PyList_GetItem($input,i);
if (PyString_Check(o))
$2[i] = PyString_AsString(PyList_GetItem($input,i));
else {
PyErr_SetString(PyExc_TypeError,"list must contain strings");
free($2);
return NULL;
}
}
$2[i] = 0;
} else {
PyErr_SetString(PyExc_TypeError,"not a list");
return NULL;
}
}
%typemap(freearg) (char *a, MY_DIGIT **argv) {
free((MY_DIGIT *) $2);
}
..from Python I am trying
>> ptr = []
>> doIt("blah", ptr)
I thought this was the correct approach as described here:
http://www.swig.org/Doc1.3/SWIGDocumentation.html#Python_nn59
However, python comes back and says "TypeError: argument number 2: a
'MY_DIGIT **' is expected, 'list([])' is received"
..any ideas? Thanks for all the help. The python community has been
great.
