RouteToFile Method

Instructs the class to route future requests directly to a given file.

Syntax

bool RouteToFile(qint64 lFileInfo, const QString& qsFileName, int iFlags);

Remarks

This method can be called from within the CreateFile or OpenFile event to instruct the class to route any future requests against the file specified by FileInfo directly to the file at the path specified by FileName instead of firing the corresponding events. The Flags parameter is used to specify which kinds of requests should not be routed automatically (see below).

Pass the value obtained from the CreateFile or OpenFile event's FileInfo parameter for this method's FileInfo parameter.

This method returns either true or false to indicate whether routing was set up successfully. If, after this method is called successfully, the application later wishes for routing to cease, it may do one of the following:

The Flags value should be created by OR'ing together zero or more of the following flags:

Error Handling

This method returns a Boolean value; after it returns, call the GetLastErrorCode() method to obtain its 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.
