WebSep 18, 2024 · Users tend to expect accurate delays down to very low values, which isn't really practical for the CPU yielding sleep routine. The expectation is this: actual delay = nanosleep (requested delay) whereas, in reality users get this: actual delay = nanosleep (requested delay) + the fixed overheads. WebOn Linux, sleep() is implemented via nanosleep(2). See the nanosleep(2) man page for a discussion of the clock used.
