CreateOpenedFilesSnapshot Method

Creates a snapshot of information about files that are currently open.


int CreateOpenedFilesSnapshot();
INT CreateOpenedFilesSnapshot();


This method creates a snapshot of information about all files and directories in the virtual filesystem that are currently open. This information is then used to populate the OpenFile* properties, as well as the OpenHandlesCount and OpenObjectsCount properties.

Note that there will always be at least one item in the OpenFile* properties since the virtual volume itself is always inherently open.

When the application is finished working with the opened files snapshot, it must close it by calling the CloseOpenedFilesSnapshot method in order to release the associated memory. If this method is called again before an existing snapshot is closed, the class will attempt to close it before creating a new one.

Note: This method can only be called when Active is true, and cannot be called within events.

The methods and properties related to open files snapshots are not intended to be used from multiple threads at once. Applications that wish to use said methods and properties from multiple threads are responsible for employing proper thread synchronization techniques to ensure that creation, use, and cleanup of open files snapshots occurs in a thread-safe manner.

Error Handling (C++)

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
