+.Dt KINFO_GETVMMAP 3
+.Os
+.Sh NAME
+.Nm kinfo_getvmmap
+.Nd function for getting per-process memory map information
+.Sh LIBRARY
+.Lb libutil
+.Sh SYNOPSIS
+.In sys/types.h
+.In sys/sysctl.h
+.In util.h
+.Ft struct kinfo_vmentry *
+.Fn kinfo_getvmmap "pid_t pid" "size_t *cntp"
+.Sh DESCRIPTION
+This function is used for obtaining virtual memory mapping information
+of a particular process.
+.Pp
+The
+.Ar pid
+field contains the process identifier.
+This should be the a process that you have privilege to access.
+The
+.Ar cntp
+field is allows the caller to know how many records are returned.
+.Pp
+This function is a wrapper around
+.Xr sysctl 3
+with the
+.Dv KERN_PROC_VMMAP
+mib.
+While the kernel returns a packed structure, this function expands the
+data into a fixed record format.
+.Sh RETURN VALUES
+On success the
+.Fn kinfo_getvmmap
+function returns a pointer to an array of
+.Vt struct kinfo_vmentry
+structures as defined by
+.In sys/sysctl.h .
+The array was obtained by an internal call to
+.Xr malloc 3
+and must be freed by the caller with a call to
+.Xr free 3 .
+On failure the
+.Fn kinfo_getvmmap
+function returns
+.Dv NULL .
+.Sh SEE ALSO
+.Xr free 3 ,
+.\" .Xr kinfo_getfile 3 ,
+.Xr malloc 3
