Now to the questions: I'm searching for a quick and easy way to
integrate SQLite3 in my application. I came across the
etc.c.sqlite3 and the DSQLite
library(https://github.com/bioinfornatics/DSQLite).
Thinking that the C bindings is more documented I tried learning
that. Though I can't understand the arguements of the callback
function.
extern(C) int callback(
void* NotUsedAtAll, // Null variable
int argc, // What?
char** results, // Results?
char** columnNames //Column Names?
){
for(int i = 0; i<argc; i++){
writeln(results);
getchar();
}
I've been reading through many explanations about this and I
understand why the callback is needed but I can't seem to
understand how to really use the callback function. Can someone
provide a brief explanation or just point me in the right
direction?
May as well throw an undocumented library at you:

I only used it to pull data out of SQLite database. Once you have
your db object it is something like this.
foreach(data; db.query(statement).range!Structure)...
Where you define a struct with Nullable!() types your statement
pulls out.
