Returns the time resolution returned by POSIX clock_getres() function.
clock_id specifies a kind of clock. See the document of Process.clock_gettime for details.
clock_id can be a symbol as Process.clock_gettime. However the result may not be accurate. For example, +Process.clock_getres(:GETTIMEOFDAY_BASED_CLOCK_REALTIME)+ returns 1.0e-06 which means 1 microsecond, but actual resolution can be more coarse.
If the given clock_id is not supported, Errno::EINVAL is raised.
unit specifies a type of the return value. Process.clock_getres accepts unit as Process.clock_gettime. The default value, :float_second, is also same as Process.clock_gettime.
Process.clock_getres also accepts :hertz as unit. :hertz means a the reciprocal of :float_second.
:hertz can be used to obtain the exact value of the clock ticks per second for times() function and CLOCKS_PER_SEC for clock() function.
+Process.clock_getres(:TIMES_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns the clock ticks per second.
+Process.clock_getres(:CLOCK_BASED_CLOCK_PROCESS_CPUTIME_ID, :hertz)+ returns CLOCKS_PER_SEC.
p Process.clock_getres(Process::CLOCK_MONOTONIC) #=> 1.0e-09
This method is called automatically when a new SSLSocket is created. However, it is not thread-safe and must be called before creating SSLSocket objects in a multi-threaded program.
Reads length bytes from the SSL connection. If a pre-allocated buffer is provided the data will be written into it.
Checks that cert signature is made with PRIVversion of this PUBLIC ‘key’
key - the public key to be used for verifying the SPKI signature
Returns true if the signature is valid, false otherwise. To verify an SPKI, the public key contained within the SPKI should be used.
Verifies this request using the given certificates and store. certificates is an array of OpenSSL::X509::Certificate, store is an OpenSSL::X509::Store.
Creates an OpenSSL::OCSP::Response from status and basic_response.
Verifies the signature of the response using the given certificates and store. This works in the similar way as OpenSSL::OCSP::Request#verify.
