The proper way is to call os.sysconf('SC_CLK_TCK') but that is not easy to<br>
do on Android/CrOS. In practice, nearly all Linux machines have a USER_HZ<br>
of 100, so just return that.</tt></dd></dl>

<br>
Currently this is only implemented on Windows. See<br>
crbug.com/424024 for background on why it was added.<br>
<br>
Args:<br>
proc: a process object returned from subprocess.Popen.<br>
app_name: on Windows, is the prefix of the application's window<br>
class name that should be searched for. This helps ensure<br>
that only the application's windows are closed.<br>
<br>
Returns True if it is believed the attempt succeeded.</tt></dd></dl>

Which MSRs are available depends on the CPU model.<br>

Args:<br>
msr_number: The number of the register to read.<br>
start: The least significant bit to read, zero-indexed.<br>
(Said another way, the number of bits to right-shift the MSR value.)<br>
length: The number of bits to read. MSRs are 64 bits, even on 32-bit CPUs.</tt></dd></dl>
