times - get process times

Syntax

#include <sys/times.h> clock_t times(struct tms *buffer) ;

Description times() fills the tms structure pointed to by buffer with information on execution times (see

	sys/times.h). All time specifications are defined in terms of the number of clock ticks used. The execution times of a terminated child process are included in the tms_cutime and tms_cstime components of the parent process when the wait() function returns the process ID of the terminated child process. If a child process does not wait for its children, their times are not included. The tms_utime structure member is the CPU time used for the execution of user instructions of the calling process. The tms_stime structure member is the CPU time used for the execution of system statements on behalf of the calling process. The tms_cutime structure member is the sum of the tms_utime and tms_cutime times of the child processes. The tms_cstime structure member is the sum of the tms_stime and tms_cstime times of the child processes.
Return val.	Elapsed real time, in clock ticks, since a particular point in time
		(e.g. since the system was activated). This point in time does not change from one times() function call within a process to another. The value returned may exceed the possible value range of type clock_t (overflow).
	(clock_t)-1	if an error occurs. errno is set to indicate the error.
Notes	Portable applications should use the function sysconf(_SC_CLK_TCLK) to determine the number of clock ticks per second, since this value may vary from system to system.
