BridJ: Add support for time_t

[GoogleCodeExporter]

As suggested in issue #68, we could add a TimeT class like the SizeT one... to 
be investigated !

Hi Olivier,

Thanks!
I use "@Ptr long" for time_t mapping at present, but it doesn't look 100% 
correct
(as follows from the discussion you mentioned).

So I think that TimeT is necessary. Or may be you have other suggestion?

Regards, Andrei.

I need "struct timeval" implemented correctly (used in Pcap pcap_pkthdr and 
V4L2 v4l2_buffer structures).

timeval definition is 
(http://pubs.opengroup.org/onlinepubs/007908799/xsh/systime.h.html):

The <sys/time.h> header defines the timeval structure that includes at least 
the following members:

time_t         tv_sec      seconds
suseconds_t    tv_usec     microseconds

What is the best approach in this case?

Regards, Andrei.

Hi Olivier,

Regarding "timeval" structure:
Timeval structure is defined as
typedef struct timeval {
  long tv_sec;
  long tv_usec;
} timeval;
on Windows (http://msdn.microsoft.com/en-us/library/ms740560%28v=vs.85%29.aspx),
so it looks differently (in general case) than timeval from <sys/time.h> 
(mentioned above)...

Is it possible to define timeval mapping in BridJ API also?

Regards, Andrei.

Hi Andrei,

Supporting time_t and timeval requires quite a bit of work, since they're 
different on virtually every platform, but it's definitely doable. I'm thinking 
about how to proceed right now... will keep you updated !

Hi Olivier,

Afaik JNA doesn't provide timeval/time_t mapping class. Right?
Thanks for accepting and working on this features!!!

Regards, Andrei.

Hi Andrei,

Just so you know, I've just enhanced the struct customization mechanism in 
BridJ, so timeval should be easier to implement (I've added an untested binding 
for it) :
https://github.com/ochafik/nativelibs4java/commit/402e637b3c4b11a7a2c9270ac67436

As for time_t, I'm still considering various implementation options, stay tuned 
!
Cheers

Hi Olivier,

Great. Thanks.
I suppose org.bridj.TimeT.timeval should be static class?

Regards, Andrei.
