|---|---|
CL_MEM_READ_WRITE |
This flag specifies that the memory object will be read and written by a kernel. This is the default. |
CL_MEM_WRITE_ONLY |
This flags specifies that the memory object will be written but not read by a kernel. Reading from a buffer or image object created with |
CL_MEM_READ_ONLY |
This flag specifies that the memory object is a read-only memory object when used inside a kernel. Writing to a buffer or image object created with |
CL_MEM_USE_HOST_PTR |
This flag is valid only if OpenCL implementations are allowed to cache the buffer contents pointed to by The result of OpenCL commands that operate on multiple buffer objects created with the same |
CL_MEM_ALLOC_HOST_PTR |
This flag specifies that the application wants the OpenCL implementation to allocate memory from host accessible memory.

This flag is valid only if
