with my test of gettimeofday in cygwin it appears to be counting in
milliseconds
rather than microseconds.
so I had a look at where it is coded, /winsup/cygwin/times.cc
...
gettimeofday (struct timeval *tv, void *tzvp)
{
struct timezone *tz = (struct timezone *) tzvp;
static bool tzflag;
LONGLONG now = gtod.usecs ();
...
I notice there is
hires_ms NO_COPY gtod;
however lower down there is appears to be a hires_us
class coded.
So I am wondering what the story is behind this ?
I will look at testing some changes here and testing, just need to do a
successful build from source
of as is first.....
I am looking for microsecond resolution, and see that hires_us is using
QueryPerformanceFrequency/QueryPerformanceCounter,
so thats looking good I think?
I have code that does bitbanging to the parallel port, it works
perfectly under linux, and would like
to see it work in cygwin also.
Thanks
