Release Event

Fires when the OS needs to release (close) a file.

Syntax

class FUSEReleaseEventParams {
public:
  const QString &Path();
  int FileContext();
  int Flags();
  int Result();
  void SetResult(int iResult);
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void Release(FUSEReleaseEventParams *e);

// Or, subclass FUSE and override this emitter function.
virtual int FireRelease(FUSEReleaseEventParams *e) {...}

Remarks

This event fires when the OS wants to close the file identified by either Path or FileContext.

The Flags parameter contains the same value as the one passed during file creation or opening. Windows: if the file is opened two or more times concurrently (i.e., several open handles exist), this parameter will contain the flags of the last open operation rather than of an operation that opened a handle being closed.

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 negative error code value (e.g. -ENOENT to indicate that the file does not exist) to report an appropriate error. Please refer to the Error Reporting and Handling topic for more information.
