KINFO_GETVMOBJECT(3) FreeBSD Library Functions Manual KINFO_GETVMOBJECT(3)
NAME
kinfo_getvmobject - function for getting system-wide memory information
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <sys/types.h>
#include <sys/user.h>
#include <libutil.h>
struct kinfo_vmobject *
kinfo_getvmobject(int *cntp);
DESCRIPTION
This function is used to obtain information about the objects using
memory in the system.
The cntp argument allows the caller to know how many records are
returned.
This function is a wrapper around the "vm.objects" sysctl(3) MIB. While
the kernel returns a packed structure, this function expands the data
into a fixed record format.
RETURN VALUES
On success the kinfo_getvmobject() function returns a pointer to an array
of struct kinfo_vmobject structures as defined by <sys/user.h>. The
array is allocated by an internal call to malloc(3) and must be freed by
the caller with a call to free(3). On failure the kinfo_getvmobject()
function returns NULL.
SEE ALSO
free(3), kinfo_getvmmap(3), malloc(3)
HISTORY
The kinfo_getvmobject() function first appeared in FreeBSD 10.2.
