2 usertime - user 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 user mode. Time spent in the
13 kernel executing system calls is not included.
15 On non-POSIX based systems, this function will always return 0.
16 In particular, most MS windows based systems do not have the required
17 POSIX system call and so this function will always return 0.
20 The result for this example will depend on the speed of the CPU
21 and precision of the operating CPU time accounting sub-system:
24 ; x = ptest(2^4253-1);
29 On non-POSIX based systems, this function always returns 0.
