Detailed Description

Filesystem Specific Attributes (FSA) class.

this class handle the storage of attributes into and from the archive it has not filesystem specific knownledge. This aspect is managed by filesystem_specific_attribute_list that upon system call will create the liste of FSA and given the list of FSA will try to set them back to the filesystem

Constructor & Destructor Documentation

filesystem_specific_attribute()

libdar::filesystem_specific_attribute::filesystem_specific_attribute ( fsa_family  f )

inline

constructor used to before reading the FSA from filesystem

Note

when the underlying filesystem does not support the requested EA the constructor of the inherited class should throw an exception of type Erange. Only valid object should be built, that is object containing the value of the FSA found on the filesystem.
