zx_vmar_destroy

NAME

vmar_destroy - destroy a virtual memory address region

SYNOPSIS

#include <zircon/syscalls.h>

zx_status_t zx_vmar_destroy(zx_handle_t vmar_handle);

DESCRIPTION

vmar_destroy() unmaps all mappings within the given region, and destroys all sub-regions of the region. Note that this operation is logically recursive.

This operation does not close vmar_handle. Any outstanding handles to this VMAR will remain valid handles, but all VMAR operations on them will fail.

RETURN VALUE

vmar_destroy() returns ZX_OK on success.

ERRORS

ZX_ERR_BAD_HANDLE vmar_handle is not a valid handle.

ZX_ERR_WRONG_TYPE vmar_handle is not a VMAR handle.
