This function obtains the attributes of a function specified via entry. The parameter entry can either be a pointer to a function that executes on the device, or it can be a character string specifying the fully-decorated (C++) name of a function that executes on the device. The parameter specified by entry 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 |
| entry | - Function to get attributes of |
- Returns:
- cudaSuccess, cudaErrorInitializationError, cudaErrorInvalidDeviceFunction
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.

- cudaConfigureCall, cudaFuncSetCacheConfig (C++ API), cudaFuncGetAttributes (C API), cudaLaunch (C++ API), cudaSetDoubleForDevice, cudaSetDoubleForHost, cudaSetupArgument (C++ API)
