Cannot compile some simple D code

Question

I'm compiling some simple code:

import std.c.time;
.
.
.
timespec zero;
nanosleep(&zero, null);
.
.
.

What I get is:

Error: undefined identifier timespec
Error: undefined identifier nanosleep

std.c.time is merely a shortcut to C's time.h. If I call other functions defined in time.h, say clock(), it's Ok. If I write analogous code in C (with nanosleep()), it's Ok. In time.h I see that timespec and nanosleep declarations are put under some #ifdef, possibly it has something to do with my problem ?

How can I get it to compile ?

My working environment is: dmd v2.059 Ubuntu 12.04

Answer 1

timespec and nanosleep is mentioned exactly 0 times in the C99 standard. It's not part of standard C, can not be found in a standard time.h file and thus can not be found in std.c.time.
