7.5 oskit_dir: Directory Interface

 

The oskit_dir COM interface defines an interface for operating on a directory. The interface does not imply any per-open state; per-open methods are defined by the oskit_openfile COM interface.

The oskit_dir COM interface inherits from the oskit_file COM interface, and has the following additional methods:

lookup

Lookup a file in this directory.

create

Create a regular file in this directory.

link

Link a file into this directory.

unlink

Unlink a file from this directory.

rename

Rename a file from this directory.

mkdir

Create a directory in this directory.

rmdir

Remove a directory from this directory.

getdirentries

Read entries from this directory.

mknod

Create a special file in this directory.

symlink

Create a symlink in this directory.

reparent

Create a virtual directory from this directory.

Additionally, an oskit_dir object may export a oskit_absio COM interface; this may be determined by querying the object.

All name parameters to directory methods must be a single component, ie an entry in one of the specified directories. With the exception of rename, name parameters always refer to entries in the target directory itself.
