KINFO_GETVMMAP(3) BSD Library Functions Manual KINFO_GETVMMAP(3)NAMEkinfo_getvmmap — function for getting per-process memory map information
LIBRARY
System Utilities Library (libutil, -lutil)
SYNOPSIS
#include <sys/types.h>
#include <libutil.h>
struct kinfo_vmentry *
kinfo_getvmmap(pid_t pid, int *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 privilige 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/user.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.
