NAME
vmem_walk, vmem_size — walk a (sub-)set of the segments in a vmem arena
SYNOPSIS
#include <sys/vmem.h>
void
vmem_walk(
vmem_t *vmp,
int typemask,
void (*func)(void *, void *, size_t),
void *arg);
size_t
vmem_size(
vmem_t *vmp,
int typemask);
INTERFACE LEVEL
illumos DDI specific
PARAMETERS
-
vmp
-
The vmem arena to walk.
-
typemask
-
A bitmask indicating the types of segment to operate on.
-
VMEM_ALLOC
-
Allocated segments.
-
VMEM_FREE
-
Free segments.
-
func
-
The function to apply to each segment matching typemask. func should accept 3 arguments and return void:
-
void *arg
-
The arg passed to vmem_walk().
-
void *vaddr
-
The base address of the segment.
-
size_t size
-
The size of the segment.
-
arg
-
An arbitrary argument passed to each call to func().
DESCRIPTION
vmem_walk() walks each segment in the arena
vmp and applies
func to each which matches
typemask.
vmem_size() walks each segment in the arena
vmp and totals the size of each matching
typemask.
CONTEXT
This function may be called from user or kernel context.
