Method: FFI::Libfuse::FuseOperations#open

Defined in:
lib/ffi/libfuse/fuse_operations.rb

#open(path, fuse_file_info) ⇒ Integer

This method is abstract.

File open operation

No creation (O_CREAT, O_EXCL) and by default also no truncation (O_TRUNC) flags will be passed to open(). If an application specifies O_TRUNC, fuse first calls truncate() and then open(). Only if 'atomic_o_trunc' has been specified and kernel version is 2.6.24 or later, O_TRUNC is passed on to open.

Unless the 'default_permissions' mount option is given, open should check if the operation is permitted for the given flags.

Optionally open may also return an arbitrary filehandle in the fuse_file_info structure, which will be passed to all file operations.

Parameters:

Returns:

  • (Integer) —

    0 for success or -ve errno
