pub unsafe extern "C" fn GC_set_time_limit_tv(arg1: GC_timeval_s)Expand description
Set/get the time limit of the incremental collections. This is
similar to GC_set_time_limit and GC_get_time_limit but the time
is provided with the nanosecond precision. The value of tv_nsec
part should be less than a million. If the value of tv_ms part is
GC_TIME_UNLIMITED, then tv_nsec part is ignored. Initially, the
value of tv_nsec part of the time limit is zero. The functions do
not use any synchronization. Defined only if the library has been
compiled without NO_CLOCK macro defined.
