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
Returns the octet string representation of the elliptic curve point.
conversion_form specifies how the point is converted. Possible values are:
:compressed
:uncompressed
:hybrid
Determines whether the given ‘requirement` is satisfied by the given `spec`, in the context of the current `activated` dependency graph.
@param [Object] requirement @param [DependencyGraph] activated the current dependency graph in the
resolution process.
@param [Object] spec @return [Boolean] whether ‘requirement` is satisfied by `spec` in the
context of the current `activated` dependency graph.
Returns AST nodes under this one. Each kind of node has different children, depending on what kind of node it is.
The returned array may contain other nodes or nil.
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.
A description of the current connection state. This is for diagnostic purposes only.
