Re: using cdata in python

See: %cstring_output_allocate_size(parm, szparm, release)

Here: http://www.swig.org/Doc1.3/Library.html#Library_nn12

This worked will for me (in python) when I needed to return binary data as a string.

Subject: [Swig-user] using cdata in python

Hi there,

  I cannot understand how to use cdata to do this simple task. Let say
I have this class:

class A
{
public:
  unsigned int GetLength();
  void GetBuffer(char *strout);
};

In C++ you would use it this way:

A a;
char *buffer = new char[a.GetLength()];
a.GetBuffer(buffer);

I would like that it behave juste like python: readlines() function.
It should return the properly allocated string as a PyString (may
contains NULL character).

Thanks a bunch !
