KVM_GETCPTIME(3)       FreeBSD Library Functions Manual	      KVM_GETCPTIME(3)

NAME
     kvm_getcptime -- fetch global CPU time statistics

LIBRARY
     Kernel Data Access	Library	(libkvm, -lkvm)

SYNOPSIS
     #include <sys/param.h>
     #include <sys/resource.h>
     #include <sys/sysctl.h>
     #include <kvm.h>

     int
     kvm_getcptime(kvm_t *kd, long *cp_time);

DESCRIPTION
     The kvm_getcptime() function stores the global CPU	time statistics	from
     the kernel	kd in the array	of counters pointed to by cp_time.  Note that
     cp_time should point to an	array of CPUSTATES long	integers.  The format
     of	the counters is	identical to that output by the	kern.cp_time sysctl.

CACHING
     This function caches the nlist values for various kernel variables	which
     it	reuses in successive calls.  You may call the function with kd set to
     NULL to clear this	cache.

RETURN VALUES
     The kvm_getcptime function	returns	0 on success and -1 on failure.	 If an
     error occurs, then	an error message may be	retrieved via kvm_geterr(3).
