NAME
kinfo_getvmmap —
function for getting per-process memory
map information
LIBRARY
library “libutil”
SYNOPSIS
#include
<sys/types.h>
#include <sys/sysctl.h>
#include <util.h>
struct kinfo_vmentry *
kinfo_getvmmap(pid_t
pid, size_t
*cntp);
DESCRIPTION
This function is used for obtaining virtual memory mapping information of a particular process.The pid field contains the process identifier. This should be the a process that you have privilege to access. The cntp field is allows the caller to know how many records are returned.
This function is a wrapper around
sysctl(3) with the KERN_PROC_VMMAP mib. While
the kernel returns a packed structure, this function expands the data into a
fixed record format.
RETURN VALUES
On success the kinfo_getvmmap() function
returns a pointer to an array of struct kinfo_vmentry
structures as defined by
<sys/sysctl.h>. The array
was obtained by an internal call to
malloc(3) and must be freed by the caller with a call to
free(3). On failure the kinfo_getvmmap()
function returns NULL.
