TIMES(3C)																 TIMES(3C)

NAME
times - get process times SYNOPSIS
#include <sys/types.h> #include <sys/times.h> times(buffer) struct tms *buffer; DESCRIPTION
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. This is the structure returned by times: The children times are the sum of the children's process times and their children's times. SEE ALSO
time(1), getrusage(2), wait3(2), time(3) 4th Berkeley Distribution May 9, 1985 TIMES(3C)

NAME
times -- process times LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <sys/times.h> clock_t times(struct tms *tp); DESCRIPTION
This interface is obsoleted by getrusage(2) and gettimeofday(2). The times() function returns the value of time in CLK_TCK's of a second since 0 hours, 0 minutes, 0 seconds, January 1, 1970, Coordinated Universal Time. It also fills in the structure pointed to by tp with time-accounting information. The tms structure is defined as follows: struct tms { clock_t tms_utime; clock_t tms_stime; clock_t tms_cutime; clock_t tms_cstime; }; The elements of this structure are defined as follows: tms_utime The CPU time charged for the execution of user instructions. tms_stime The CPU time charged for execution by the system on behalf of the process. tms_cutime The sum of the tms_utimes and tms_cutimes of the child processes. tms_cstime The sum of the tms_stimes and tms_cstimes of the child processes. All times are in CLK_TCK's of a second. The times of a terminated child process are included in the tms_cutime and tms_cstime elements of the parent when one of the wait(2) func- tions returns the process ID of the terminated child to the parent. If an error occurs, times() returns the value ((clock_t)-1), and sets errno to indicate the error. ERRORS
The times() function may fail and set the global variable errno for any of the errors specified for the library routines getrusage(2) and gettimeofday(2). SEE ALSO
time(1), getrusage(2), gettimeofday(2), wait(2) STANDARDS
The times() function conforms to IEEE Std 1003.1-1988 (``POSIX.1''). BSD
