Fires before a file is resized.
The 'callback' is called when the 'BeforeSetFileSize' event is emited.
The argument 'e' has the following properties:
e.fileName e.size e.fileContext e.handleContext e.processRequest e.resultCode
This event fires before the file specified by FileName is resized, whether explicitly (e.g., truncation) or implicitly (i.e., as data is appended).
Applications may use this event to modify the request's parameters.
The Size parameter specifies the new file size, in bytes.
The FileContext and HandleContext parameters are placeholders for application-defined data associated with the file and specific handle, respectively. Please refer to the Contexts topic for more information. (If the system's cache manager or memory manager initiated the operation, HandleContext may be absent, in which case it will be .)
The ProcessRequest parameter controls whether the request is sent onwards for further processing by subsequent filter drivers and the filesystem; it is true by default.
The ResultCode parameter will always be 0 when the event is fired. If the event cannot be handled in a "successful" manner for some reason (e.g., a resource isn't available, security checks failed, etc.), set it to a non-zero value to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
This event is fired synchronously; please refer to the Event Types topic for more information.
