This function obtains the attributes of a function specified via func. func is a device function symbol and must be declared as a __global__ function. The fetched attributes are placed in attr. If the specified function does not exist, then cudaErrorInvalidDeviceFunction is returned.
Note that some function attributes such as maxThreadsPerBlock may vary based on the device that is currently being used.
- Parameters:
-
| attr | - Return pointer to function's attributes |
| func | - Function to get attributes of |
- Returns:
- cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidDeviceFunction
- Note:
- The
func paramater may also be a character string that specifies the fully-decorated (C++) name for a function that executes on the device, however this usage is deprecated as of CUDA 4.1.
Note that this function may also return error codes from previous, asynchronous launches.
