I'm trying to make fuse work in D[1]. I had some help from htod, but not
everything was successful. And I'm not exactly sure how to properly convert
strings and such.
What I currently have allows me to compile some fuse programs (hello for
example[2]). But the result is a dead link (only seem to be able to fix it by
rebooting). Anyway the specific questions I want to get out of the way are as
follows.
hello_str = cast(char*) toStringz("Hello World!\n");
I stopped doing this, but I'm just wondering how you could get a modifiable C
string if I needed one?
fuse.d:669 auto user_data = new ubyte[78];
fuse.d:670 return fuse_main_real(cast(int) argc, argv, op, (*(op)).sizeof,
user_data.ptr);
[3]This is likely a big part of the problem, but I just didn't understand the
C. It is a defined as:
#define fuse_main(argc, argv, op, user_data) \
fuse_main_real(argc, argv, op, sizeof(*(op)), user_data)
But is called:
return fuse_main(argc, argv, &hello_oper);
And I can't find a three argument fuse_main. So I made one and just passed a
block of storage (converting to a pointer so the compiler wouldn't complain of
conversions and I didn't cast)
Then there is a structure which had some padding, and htod didn't fully convert
it, leaving off two fields at the end[4]. Maybe I should move them to just
after the bit field? I think it would be fine...
The last one is the node structure[5]. Which I found in fuse.c[6] but seems to
be used a lot so I don't no why it isn't in a header. This used the is_hidden :
1 notation so I created some bit fields, but it didn't have padding like the
others, so I don't know if I did this correctly.
This is probably trivial bindings for those who know C better, but it has been
fun. The links are below, and I was using the 2.8.4 header files.
