I've got two different Python extension modules; let's call them A and B. Module A contains a storage class type called container that I want to use within Module B as the return type of a class method. I can't seem to find any documentation on how I'm supposed to do this. I roughly followed this article to create the modules/classe...
Hi all, I've written a simple library file with a function for reading lines from a file of any size. The function is called by passing in a stack-allocated buffer and size, but if the line is too big, a special heap-allocated buffer is initialized and used to pass back a larger line. This heap-allocated buffer is function-scoped and d...
Hi, In my c/c++ files, there are multiple #define. As an example: #ifdef LIBVNCSERVER_HAVE_LIBZ /* some code */ #ifdef LIBVNCSERVER_HAVE_LIBJPEG /* some more code */ Can you please tell me how can I modify my Makefile.in so that I have those #define in ALL files during compilation? Thank you. ...

How can I print a non-null-terminated string using printf, assuming that I know the length of the string at runtime? ...
I'm currently working with a SPC that supports ANSI C, but uses its own flavour of the GNU compiler, which doesn't compile any variadic functions and things like itoa. So using sprintf & co. isn't an option for converting integers to strings. Can anyone guide me to a site where a robust, sprintf- free implementation of itoa is listed or ...

Possible Duplicates: What is Type-safe? What is type-safety? I was reading about c++ vectors and it was mentioned that memcpy and printf functions from C are not type safe.
