Function ocl_core::enqueue_read_buffer_rect

[src]
pub unsafe fn enqueue_read_buffer_rect<T: OclPrm>(command_queue: &CommandQueue,
buffer: &Mem,
block: bool,
buffer_origin: [usize; 3],
host_origin: [usize; 3],
region: [usize; 3],
buffer_row_pitch: usize,

-> OclResult<()>
Enqueues a command to read from a rectangular region from a buffer object to host memory.
Safety
Caller must ensure that data lives until the read is complete. Use
new_event to monitor it (use [core::EventList::last_clone] if passing
an event list as new_event).
