This event fires when the OS wants to change the Windows security attributes of the file or directory specified by FileName.
This event only needs to be handled if the use_windows_security property is enabled. To handle this event properly, applications must update the pieces of security information, specified by SecurityInformation, on the specified file or directory in their backend storage. Please refer to the parameter descriptions below, as well as the Security Checks topic, for more information.
The SecurityInformation parameter indicates which pieces of security information must be set. This value is a bitfield; possible flags include (but are not limited to):
The SecurityDescriptor parameter points to a memory buffer that contains data indicated by SecurityInformation. This data is formatted as a SECURITY_DESCRIPTOR structure in self-relative format. Please refer to those articles for more information about self-relative security descriptors.
The Length parameter specifies the length, in bytes, of SecurityDescriptor.
Please refer to the Buffer Parameters topic for more information on how to work with memory buffer event parameters.
The HandleInfo parameter carries a handle to an object with information about the file handle. While within the event handler, it can be used to call any of the following methods: get_handle_creator_process_id, get_handle_creator_process_name, get_handle_creator_thread_id, or get_handle_creator_token.
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.
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.
