Parameters

name	path name, relative to the local filesystem
pstat	file information is stored here

Returns

0 on success, or a negative number on failure

Implements miosix::FilesystemBase.

virtual

Create a directory

Parameters

name	directory name
mode	directory permissions

Returns

0 on success, or a negative number on failure

Implements miosix::FilesystemBase.

int miosix::MountpointFs::open ( intrusive_ref_ptr< FileBase > &  file, StringPart &  name, int  flags, int  mode  )

virtual

Open a file

Parameters

file	the file object will be stored here, if the call succeeds
name	the name of the file to open, relative to the local filesystem
