The following table describes other data types supported by OpenCL:
Type | Description |
---|---|
image2d_t | A 2D image. See individual Image Functions for more information. |
image3d_t | A 3D image. See individual Image Functions for more information. |
image2d_array_t | A 2D image array. See individual Image Functions for more information. |
image1d_t | A 1D image. See individual Image Functions for more information. |
image1d_buffer_t | A 1D image created from a buffer object. See individual Image Functions for more information. |
image1d_array_t | A 1D image array. See individual Image Functions for more information. |
image2d_depth_t | A 2D depth image. See individual Image Functions for more information. |
image2d_array_depth_t | A 2D depth image array. See individual Image Functions for more information. |
sampler_t | A sampler type. |
queue_t | A device command queue. This queue can only be used to enqueue commands from kernels executing on the device. |
ndrange_t | The N-dimensional range over which a kernel executes. |
clk_event_t | A device side event that identifies a command enqueue to a device command queue. |
reserve_id_t | A reservation ID. This opaque type is used to identify the reservation for reading and writing a pipe. Refer to section 6.13.16. |
event_t | An event. This can be used to identify async copies from global to local memory and vice-versa. See individual Async Copy and Prefetch Functions for more information. |
cl_mem_fence_flags |
This is a bitfield and can be 0 or a combination of the
following values ORed together:
These flags are described in detail in section 6.13.8 of the OpenCL specification (see syncFunctions). |
image2d_msaa_t | If the cl_khr_gl_msaa_sharing extension is enabled: A 2D multi-sample color image. |
image2d_array_msaa_t | If the cl_khr_gl_msaa_sharing extension is enabled: A 2D multi-sample color image array. |
image2d_msaa_depth_t | If the cl_khr_gl_msaa_sharing extension is enabled: A 2D multi-sample depth image. |
image2d_array_msaa_depth_t | If the cl_khr_gl_msaa_sharing extension is enabled: A 2D multi-sample depth image array. |
NOTE: The image2d_t, image3d_t, image2d_array_t,
image1d_t, image1d_buffer_t, image1d_array_t,
image2d_depth_t, image2d_array_depth_t
and sampler_t types are only defined if the device
supports images i.e. CL_DEVICE_IMAGE_SUPPORT
is CL_TRUE
. See the table for param_name
for
clGetDeviceInfo for details.
The C99 derived types (arrays, structs, union, function, and pointers), constructed from the built-in data types described in Scalar Data Types, Vector Data Types, and Other Data Types are also supported with certain restrictions described in section 6.9.
The following tables describe the other built-in data types in OpenCL described in table 6.3 and the corresponding data type available to the application:
Type in OpenCL C | API type for application |
---|---|
queue_t | cl_command_queue |
clk_event_t | cl_event |
