I'm using python 2.4 under linux (centos 5.1).
I need to pass an array of doubles to a c function
but am getting an error, shown near the bottom of
this post.
----------------------------------------------------
my swig interface file looks like this
* File: rug520.i */
%module rug520
%include "typemaps.i"
%include "carrays.i"
%array_class(double, doubleArray);
%{
#define SWIG_FILE_WITH_INIT
#include "rug520.h"
extern double[] nCmiArray;
%}
%apply int *OUTPUT { char *sRugHier,
char * sRugMax,
int * iRugHier,
int * iRugMax,
double * nCmiValueHier,
double * nCmiValueMax,
int * iAdlSum,
int * iCpsCode,
char * sRugsVersion,
char * sDllVersion,
int * iError };
int RugCalc( char * sMdsRecord,
char * sRehabType,
char * sModel,
int iQuarterlyFlag,
double nCmiArray[],
char * sRugHier,
char * sRugMax,
int * iRugHier,
int * iRugMax,
double * nCmiValueHier,
double * nCmiValueMax,
int * iAdlSum,
int * iCpsCode,
char * sRugsVersion,
char * sDllVersion,
int * iError );
------------------------------------------------------------------
my test code looks like this:
import sys, os, rug520
cmi=[0.0] *59
def getrug(mds):
results = rug520.RugCalc(mds, 'mcare', '34', 0, cmi)
print 'results', results
datafile = open('mdsdata.txt')
for d in datafile:
if d[0]=='B':
getrug(d)
------------------------------------------------------------------------
I get this error message
File "testrug520.py", line 11, in ?
getrug(d)
File "testrug520.py", line 5, in getrug
results = rug520.RugCalc(mds, 'mcare', '34', 0, cmi)
TypeError: in method 'RugCalc', argument 5 of type 'double []'
--------------------------------------------------------------------------
I'm guessing that I am not passing a double array to the c code. I cannot
change
the c code due to politics. I could write a c "wrapper" if I had to, but would
rather
stay within python or the swig interface definitions if possible/practical.
I'm not much of a c programmer; mostly java and python with a little c++.
I've looked in the swig docs and tried google, but either have not found
it or just don't understand what they are telling me here.
