Struct ocl_core::types::structs::BufferRegion
source · pub struct BufferRegion<T> { /* private fields */ }
Expand description
Defines a buffer region for creating a sub-buffer.
Info (from SDK)
(origin, size) defines the offset and size in bytes in buffer.
If buffer is created with CL_MEM_USE_HOST_PTR, the host_ptr associated with the buffer object returned is host_ptr + origin.
The buffer object returned references the data store allocated for buffer and points to a specific region given by (origin, size) in this data store.
CL_INVALID_VALUE is returned in errcode_ret if the region specified by (origin, size) is out of bounds in buffer.
CL_INVALID_BUFFER_SIZE if size is 0.
CL_MISALIGNED_SUB_BUFFER_OFFSET is returned in errcode_ret if there are no devices in context associated with buffer for which the origin value is aligned to the CL_DEVICE_MEM_BASE_ADDR_ALIGN value.
