NAME

       clIcdGetPlatformIDsKHR - Obtain the list of platforms accessible through the Khronos ICD Loader.

       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.
