In POSIX there is gettimeofday() and in Win32 there is GetTickCount().
On Win32, GetTickCount() will give better than microsecond precision.
The precision on linux and *BSD depends on the architecture. On most
architectures, including i386, the entire one microsecond resolution
of the datatype will be usable.

If you dig into the glib source code you should be able to determine the
suitability of the GTimer interface to your application.
