Actually, they involved very similar modern 64 bit code meeting classic 32 bit code” “The thrsleep system call is a part of the kernel code that supports threads. As the name implies, it gives userland a measure of control over scheduling and lets a thread sleep until something happens. As such, it takes a timeout in the form of a timespec. The kernel, however, internally implements time keeping using ticks (there are HZ, 100, ticks per second).
