class SharedVmo

Defined at line 23 of file ../../src/lib/fsl/vmo/shared_vmo.h

Holds a reference to a shared VMO which may be memory mapped lazily.

Once memory-mapped, the VMO remains mapped until all references to this

object have been released.

This object is thread-safe.

Public Methods

void SharedVmo (zx::vmo vmo, uint32_t map_flags)

Initializes a shared VMO.

|vmo| must be a valid VMO handle.

If not zero, |map_flags| specifies the flags which should be passed to

|zx::vmar::map| when the VMO is mapped.
