NAME¶clGetDeviceIDs - Obtain the list of devices available on a platform.
cl_int clGetDeviceIDs(cl_platform_id platform, cl_device_type device_type, cl_uint num_entries, cl_device_id *devices, cl_uint *num_devices);
|CL_DEVICE_TYPE_CPU||An OpenCL device that is the host processor. The host processor runs the OpenCL implementations and is a single or multi-core CPU.|
|CL_DEVICE_TYPE_GPU||An OpenCL device that is a GPU. By this we mean that the device can also be used to accelerate a 3D API such as OpenGL or DirectX.|
|CL_DEVICE_TYPE_ACCELERATOR||Dedicated OpenCL accelerators (for example the IBM CELL Blade). These devices communicate with the host processor using a peripheral interconnect such as PCIe.|
|CL_DEVICE_TYPE_CUSTOM||Dedicated accelerators that do not support programs written in OpenCL C.|
|CL_DEVICE_TYPE_DEFAULT||The default OpenCL device in the system. The default device cannot be a CL_DEVICE_TYPE_CUSTOM device.|
|CL_DEVICE_TYPE_ALL||All OpenCL devices available in the system except CL_DEVICE_TYPE_CUSTOM devices.|
NOTES¶clGetDeviceIDs may return all or a subset of the actual physical devices present in the platform and that match device_type.
ERRORS¶clGetDeviceIDs returns CL_SUCCESS if the function is executed successfully. Otherwise it returns one of the following:
