cl-queue-copy-buffer ( src-buffer-ptr dst-buffer-ptr size dependent-events -- event )
OpenCL

Prev:	<cl-buffer> ( buffer-access-mode size initial-data -- buffer )
Next:	cl-read-buffer ( buffer-range -- byte-array )

Vocabulary
opencl

Inputs

src-buffer-ptr	a cl-buffer-ptr
dst-buffer-ptr	a cl-buffer-ptr
size	an integer
dependent-events	sequence of events

Outputs

event

a cl-event

Word description
Queue a copy operation from src-buffer-ptr to dst-buffer-ptr. Dependent events can be passed to order the operation relative to other operations.
