Other Data Types

Other Built-in Data Types

Description

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.
sampler_t A sampler type.
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.

NOTE: The image2d_t, image3d_t, image2d_array_t, image1d_t, image1d_buffer_t, image1d_array_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.
