Is There a QueryPerformanceCounter Equivalent for High-Resolution Timing in Linux?

QueryPerformanceCounter Equivalent for Linux High-Resolution Timing

In the Windows operating system, developers can utilize the QueryPerformanceCounter function from the mmsystem.h header to establish a high-resolution timer. However, is there a comparable functionality available for the Linux environment?

Solutions for Linux High-Resolution Timing

Certainly, Linux offers several alternatives to achieve high-resolution timing:

• Boost ptime Function: Boost C libraries provide a ptime function, which offers a convenient interface for precise timekeeping.
• POSIX clock_gettime() Function: Linux systems support the POSIX clock_gettime() function, which allows developers to access hardware clocks and obtain high-resolution timestamps.
