libdar::tlv::type

Memory_file is a generic_file class that only uses virtual memory.
libdar::memory_file
generic_file stored in memory
Definition: memory_file.hpp:41
libdar::tlv::dump
void dump(generic_file &f) const
dumps the tlv contents to file
libdar::generic_file
this is the interface class from which all other data transfer classes inherit
Definition: generic_file.hpp:77
libdar::tlv
Definition: tlv.hpp:44
libdar::tlv::setup
void setup(generic_file &f)
same as the constructor but on an existing object
libdar
libdar namespace encapsulate all libdar symbols
