Function: synchronize_stream_with_timeout

aclError aclrtSynchronizeStreamWithTimeout(aclrtStream stream, int32_t timeout)

ret = acl.rt.synchronize_stream_with_timeout(stream, timeout)

Blocks app running until all tasks in the specified stream are complete. This API is enhanced based on acl.rt.synchronize_stream and allows you to set the timeout interval for your app.

stream: int, pointer address of the stream object that needs to complete all tasks.

timeout: int, API timeout interval. The options are as follows:

• -1: waits forever, which functions equivalently as acl.rt.synchronize_stream.
• > 0: specific timeout interval, in ms.

ret: int, error code.

• 0 indicates success.
• Other values indicate failure.
