2 systime - kernel CPU time used by the current process
8 return nonnegative real
11 In POSIX based systems, this function will return the CPU seconds
12 used by the current process while in kernel mode executing kernel
13 code on behalf of the current process. Time spent by the current
14 process executing user code (such as performing computation on
15 behalf of calc) is not counted.
17 On non-POSIX based systems, this function will always return 0.
18 In particular, most MS windows based systems do not have the required
19 POSIX system call and so this function will always return 0.
22 The result for this example will depend on the speed of the CPU
23 and precision of the operating CPU time accounting sub-system:
31 On non-POSIX based systems, this function always returns 0.
