The clock_gettime() is a function that gives the clock’s current time, which is specified by clock_id. The clock_gettime has a VDSO(Virtual Dynamic Shared Object) implementation on X86 architecture. The VDSO is a shared memory segment between the kernel and the users, allowing the kernel...
Using the appropriate macros, open file descriptors may be converted into clock IDs and passed toclock_gettime(),clock_settime(), andclock_adjtime(2). The following example shows how to convert a file descriptor into a dynamic clock ID. ...
Example 1: In WSL bash.exe: sudo apt-get install ruby. irb sleep 1 Normal behaviour: 2.5.1 :001 > sleep 1 => 1 Behaviour when issue occurs: Ruby interpreter crashes referencing pthread_cond_timedwait EINVAL. Example 2: In WSL bash.exe: ...
For this clock, the value returned by clock_gettime() represents the amount of time (in seconds and nanoseconds) since an unspecified point in the past (for example, system start-up time, or the Epoch). This point does not change after system start-up time. The value of the CLOCK_MONO...
gettime() represents the amount of time (in seconds and nanoseconds) since an unspecified point in the past (for example, system start-up time, or the Epoch). This point does not change after system start-up time. The value of the CLOCK_MONOTONIC clock cannot be set via clock_settime(...
In function 'nanotime': error: 'CLOCK_REALTIME' undeclared (first use in this function) error: (Each undeclared identifier is reported only once error: for each function it appears in.) It appears that clock_gettime is not implemented in Mac OS X. Is there an alternative means of getti...
For example, Process::CLOCK_REALTIME is defined as :GETTIMEOFDAY_BASED_CLOCK_REALTIME when clock_gettime() is not available.Emulations for CLOCK_REALTIME::GETTIMEOFDAY_BASED_CLOCK_REALTIME Use gettimeofday() defined by SUS. (SUSv4 obsoleted it, though.) The resolution is 1 microsecond. :...
The merging of the builtin time function has caused some fallout on older platforms. RHEL 6 has clock_gettime in librt, which is a reasonably easy fix in CMake which I'll try and get to shortly. However, there is no clock_gettime in macO...
