digitalmars.D.learn - Interfacing to C
- Joshua Niehus (22/22) Jun 28 2011 Hello,
Hello, I was trying to run the example on the Interfacing to C page ( http://www.d-programming-language.org/interfaceToC.html) and ran into few issues. To get it to work "as is" i was .dup(ing) strings into new chars with defined size and passing those with .ptr. Anyway it seemed like quite a bit of work for something simple so I added const in the signatures and things worked much more smoothly: import std.stdio, std.string; extern (C) int strcmp(const char* string1, const char* string2); void main() { writeln(myDfunction("foo")); } int myDfunction(const char[] s) { return strcmp(std.string.toStringz(s), "foo"); } Was there a reason why the consts were left out? if this is a typo I'd be happy to update the web page, would be good experience for a noob like me. (never used GIT before and first time participating in a community) Thanks, Josh
