Sets the VM Status according to status::success and returns the previous VM Status.
uint8_t clear_status (queue& exec_queue );
clear_status supports the following devices: Host, CPU, and GPU.
The clear_status function sets the VM status to status::success and returns the previous VM status.
The global VM Status is a single value and it accumulates all errors that happen inside VM functions. The following table lists the possible error values.
Status | Description |
---|---|
Successful Execution | |
status::success | VM function execution completed successfully |
status::not_defined | VM status not defined |
Warnings | |
status::accuracy_warning | VM function execution completed successfully in a different accuracy mode |
Computational Errors | |
status::errdom | Values are out of a range of definition producing invalid (QNaN) result |
status::sing | Values cause divide-by-zero (singularity) errors and produce and invalid (QNaN or Inf) result |
status::overflow | An overflow happened during the calculation process |
status::underflow | An underflow happened during the calculation process |
The queue where the routine should be executed.
Specifies the former VM status.
uint8_t olderr = clear_status (exec_queue);
