Freeing memory allocated at C function

I'm using some C functions like these: char *str = allocateNewString(); And this: Object *obj = constructObject(); // etc freeObject(obj); Do I need to free the memory in both cases? Can I someway register them on GC?

Converting C .h Files to D Modules

Hi all, How to convert the following struct to D? typedef struct S { int type; void *obj; } S; I didn't found anything at http://dlang.org/htomodule.html.

Re: Converting C .h Files to D Modules

Ouch, void* is the same in both languages, sorry. I addressed a new problem: typedef struct SomeFunctions { void *(*funcA)(char*, size_t); void *(*funcB)(void); } SomeFunctions; How do I convert that functions references into an D struct? On Tue, Mar 20, 2012 at 3:01 PM, Pedro Lacerda

SocketStream exceptions and disconnect handling

Dmitry, very thanks for the reply! I'm going to make a nice API and acceptance testing using some Redis tutorial. With it working well do you think that worth make project marketing considering the overall code quality? Looking the sources pedantically what's wrong? Pedro Lacerda 2012/3/5

that implement the protocol as free functions isn't a bad option because D offers this imperative style and the protocol is so small that doesn't need more a structured approach. Tell me this is wrong! thanks from a newbie :-) Pedro Lacerda

DVM is great for this: https://bitbucket.org/doob/dvm DVM sounds well, thanks! As for use cases, command line is a good bet. I suggest starting with something that has a clear scope and isn't chosen based on a marketing feature. For example if you're going to build a server of some sort

Re: Arrays - Inserting and moving data

I __believe__ that insertInPlace doesn't shift the elements, but use an appender allocating another array instead. Maybe this function do what you want. int[] arr = [0,1,2,3,4,5,6,7,8,9]; void maybe(T)(T[] arr, size_t pos, T value) { size_t i; for (i = arr.length - 1; i
