on_release Event

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

Syntax

class FUSEReleaseEventParams(object):
  @property
  def path() -> str: ...
  @property
  def file_context() -> int: ...
  @property
  def flags() -> int: ...
  @property
  def result() -> int: ...
  @result.setter
  def result(value) -> None: ...

# In class FUSE:
@property
def on_release() -> Callable[[FUSEReleaseEventParams], None]: ...
@on_release.setter
def on_release(event_hook: Callable[[FUSEReleaseEventParams], None]) -> None: ...

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.
