Method: FFI::Libfuse::FuseOperations#poll

Defined in:

lib/ffi/libfuse/fuse_operations.rb

#poll(path, fuse_file_info, ph, reventsp) ⇒ Integer

This method is abstract.

Poll for IO readiness events

Parameters:

• path (String)
• fuse_file_info (FuseFileInfo)
• ph (FusePollHandle|nil) —

  If ph is set, the client should notify when IO readiness events occur by calling FFI::Libfuse::FusePollHandle#notify_poll (possibly asynchronously)

  Regardless of the number of times poll is received, single notification is enough to clear all. Notifying more times incurs overhead but doesnt harm correctness.

• reventsp (FFI::Pointer) —

  return events

Returns:

• (Integer) —

  0 for success, -ve for error
