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).
