TIMES(3C)TIMES(3C)NAMEtimes - get process timesSYNOPSIS
#include <sys/times.h>
clock_t times(struct tms *buffer);
DESCRIPTION
For non-POSIX applications this interface is obsoleted by getrusage(2).
Times returns time-accounting information for the current process and
for the terminated child processes of the current process. All times
are in 1/HZ seconds, where HZ is 60.
The tms structure contains the following members:
Member Type Member Name
clock_t tms_utime
clock_t tms_stime
clock_t tms_cutime
clock_t tms_cstime
The times of a terminated child process are included in the tms_cutime
and tms_cstime members of the parent when a wait or waitpid function
returns the process ID of this terminated child. If a child process
has not waited for its terminated children, their times are not
included in its times.
The value tms_utime is the CPU time charged for the execution of user
intructions.
The value tms_stime is the CPU time charged for execution by the system
on behalf of the process.
The value tms_cutime is the sum of the tms_utime's s and tms_cutime's
of the child processes.
The value tms_cstime is the sum of the tms_stime s and tms_cstime s of
the child processes.
RETURN VALUE
Upon successful completion, times shall return the elapsed real time,
in clock ticks. If times fails, a value of (( clock_t )-1) is
returned.
