I am having some difficulty using an array of structures.
The C structure looks like this:

typedef struct {
char part1[100];
char part2[100];
char part3[100];
} stuff;

typedef struct {
char part1[100];
char part2[100];
char part3[100];
} something;

typedef struct {
char type[100];
char date[100];
char time[100];
stuff stuff;
something something;
} container;

typedef struct {
char text[512];
container container[1];
} message;

The Java looks like:
message info = new message();
info.text().setCString(“TEST”);
Pointer Pinfo = Pointer.pointerTo(info);

This structure is then passed to a function via the pointer type.

The container array seems to be the problem as the rest of the code was working fine before it’s addition. Is there something I need to do on the java side to initialize the array?

Thanks for any insight you can give.

Hi David,

Thanks for your report !

I've deployed a fix for BridJ's struct layout code that should solve your particular case (if not, please let me know :-)), available in the latest 0.6.2-SNAPSHOT (see https://code.google.com/p/bridj/wiki/Download ).

Cheers
