NAME

       clGetPlatformInfo - Get specific information about the OpenCL platform.

       cl_int clGetPlatformInfo(cl_platform_id platform, cl_platform_info param_name,
                                size_t param_value_size, void *param_value,
                                size_t *param_value_size_ret);

PARAMETERS

       platform
           The platform ID returned by clGetPlatformIDs(3clc) or can be NULL. If platform is
           NULL, the behavior is implementation-defined.

       param_name
           An enumeration constant that identifies the platform information being queried. It can
           be one of the values specified in the table below.

       param_value
           A pointer to memory location where appropriate values for a given param_value will be
           returned. Possible param_value values returned are listed in the table below. If
           param_value is NULL, it is ignored.

       param_value_size
           Specifies the size in bytes of memory pointed to by param_value. This size in bytes
           must be ≥ size of return type specified in the table below.

       param_value_size_ret
           Returns the actual size in bytes of data being queried by param_value. If
           param_value_size_ret is NULL, it is ignored

NOTES

       A null terminated string is returned by OpenCL query function calls if the return type of
       the information being queried is a char[].

ERRORS

       Returns CL_SUCCESS if the function is executed successfully. Otherwise, it returns the
       following:

       •   CL_INVALID_PLATFORM if platform is not a valid platform.

       •   CL_INVALID_VALUE if param_name is not one of the supported values or if size in bytes
           specified by param_value_size is less than size of return type and param_value is not
           a NULL value.

       •   CL_OUT_OF_HOST_MEMORY if there is a failure to allocate resources required by the
           OpenCL implementation on the host.
