mmio::vmo

Struct VmoMapping

Source 
pub struct VmoMapping { /* private fields */ }
Expand description

An active mapping of a Vmo in the root Vmar.

The mapped memory is kept mapped while the VmoMapping object is alive.

Implementations§

Source§

impl VmoMapping

Source

pub fn map( offset: usize, size: usize, vmo: Vmo, ) -> Result<MmioRegion<VmoMemory>, Status>

Map the specified memory range of the given Vmo in the root Vmar for this process and return an object that maintains the mapping for its lifetime.

Errors:

  • [Status::OUT_OF_RANGE]: if size > isize::MAX.
  • [Status::OUT_OF_RANGE]: if the requested region falls outside of the vmo’s memory.
  • An error returned by [zx::Vmar::map]: if the mapping fails.
