Synchronous Open Operations

  • Article

Command-line parameter:/k

During the Synchronous Open Operations, Device Path Exerciser opens an instance of the device for only synchronous I/O by using the FILE_SYNCHRONOUS_IO_ALERT create option in ZwCreateFile. If the call is successful, Device Path Exerciser uses the handle provided to perform other selected tests.

When I/O is synchronous, each I/O operation must wait for the preceding operation to complete before it begins. With the FILE_SYNCHRONOUS_IO_ALERT operation, waiting threads are alerted to the delay and can terminate the operation.

Synchronous Open Operations are not included by default. To add Synchronous Open Operations to a Device Path Exerciser test session, use the /k parameter.
