- cl_int clIcdGetPlatformIDsKHR(cl_uint num_entries, cl_platform_id *platforms, cl_uint *num_platforms);
PARAMETERS
num_entries
-
- The number of cl_platform_id entries that can be added to platforms. If platforms is not NULL, then num_entries must be greater than zero.
platforms
- Returns a list of OpenCL platforms available for access through the Khronos ICD Loader. The cl_platform_id values returned in platforms are ICD compatible and can be used to identify a specific OpenCL platform. If the platforms argument is NULL, then this argument is ignored. The number of OpenCL platforms returned is the minimum of the value specified by num_entries or the number of OpenCL platforms available.
num_platforms
- Returns the number of OpenCL platforms available. If num_platforms is NULL, then this argument is ignored.
NOTES
This function is enabled by the cl_khr_icd(3clc) extension.
ERRORS
Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns the following:
- • CL_PLATFORM_NOT_FOUND_KHR if zero platforms are available.
- • CL_INVALID_VALUE if num_entries is equal to zero and platforms is not NULL or if both num_platforms and platforms are NULL.
