18 int times(struct tms *\fIbuffer\fP)
22 returns time-accounting information
23 for the current process
24 and for the terminated child processes
25 of the current process.
26 All times are in 1/CLOCKS_PER_SEC seconds.
28 This is the structure returned by
35 clock_t tms_utime; /* user time for this process */
36 clock_t tms_stime; /* system time for this process */
37 clock_t tms_cutime; /* children's user time */
38 clock_t tms_cstime; /* children's system time */
43 The user time is the number of clock ticks used by a process on
44 its own computations. The system time is the number of clock ticks
45 spent inside the kernel on behalf of a process. This does not
46 include time spent waiting for I/O to happen, only actual CPU
49 The children times are the sum
50 of the children's process times and
51 their children's times.
54 returns 0 on success, otherwise \-1 with the error code stored into the

64 parameter is not in a valid part of the process address space.
