mask.hpp
here lies a collection of mask classes
infinint.hpp
switch module to limitint (32 ou 64 bits integers) or infinint
libdar::infinint
the arbitrary large positive integer class
Definition: real_infinint.hpp:62
libdar::mask
the generic class, parent of all masks
Definition: mask.hpp:62
libdar::archive_version
class archive_version manages the version of the archive format
Definition: archive_version.hpp:47
libdar::generic_file
this is the interface class from which all other data transfer classes inherit
Definition: generic_file.hpp:77
libdar::ea_attributs::operator+
ea_attributs operator+(const ea_attributs &arg) const
addition operator.
libdar::ea_attributs
the class ea_attributs manages the set of EA that can be associated to an inode
Definition: ea.hpp:49
libdar
libdar namespace encapsulate all libdar symbols
Definition: archive.hpp:47
