Where is gethrtime() ?

["Ernest L. Williams Jr." <ernesto@xxxxxxxx>]

Hi,

I would like to play with high resolution timers under linux and GCC.


Where is the function "gethrtime()" ?  



Is that function only found on solaris?

============= snip from a grep in /usr/include/sys ====================
time.h:extern   hrtime_t        gethrtime(void);
time.h:extern   hrtime_t        gethrtime_unscaled(void);
time.h:extern   hrtime_t        gethrtime_max(void);
time.h:hrtime_t gethrtime(void);
time.h:hrtime_t gethrtime();
=======================================================================

  



Thanks,
Ernesto
