+@deftypefun cl_int starpu_opencl_allocate_memory (cl_mem *mem, size_t size, cl_mem_flags flags)

+valid combination of cl_mem_flags values.

+Copy @var{size} bytes asynchronously from the given @var{pointer} on
+@var{src_node} to the given @var{buffer} on @var{dst_node}.
+@var{offset} is the offset, in bytes, in @var{buffer}.
+@var{event} can be used to wait for this particular copy to complete. It can be
+NULL.
+This function returns CL_SUCCESS if the copy was successful, or a valid OpenCL error code
+otherwise. The integer pointed to by @var{ret} is set to -EAGAIN if the asynchronous copy
+was successful, or to 0 if event was NULL.
