Launches the function entry on the device. The parameter entry can either be a function that executes on the device, or it can be a character string, naming a function that executes on the device. The parameter specified by entry must be declared as a __global__ function. cudaLaunch() must be preceded by a call to cudaConfigureCall() since it pops the data that was pushed by cudaConfigureCall() from the execution stack.
- Parameters:
-
| entry | - Device function pointer or char string naming device function to execute |
- Returns:
- cudaSuccess, cudaErrorInvalidDeviceFunction, cudaErrorInvalidConfiguration, cudaErrorLaunchFailure, cudaErrorLaunchTimeout, cudaErrorLaunchOutOfResources, cudaErrorSharedObjectSymbolNotFound, cudaErrorSharedObjectInitFailed
- Note:
- Note that this function may also return error codes from previous, asynchronous launches.
