libdar::user_interaction::inherited_pause
virtual bool inherited_pause(const std::string &message)=0
method used to ask a boolean question to the user.
libdar::user_interaction
This is a pure virtual class that is used by libdar when interaction with the user is required.
Definition: user_interaction.hpp:47
infinint.hpp
switch module to limitint (32 ou 64 bits integers) or infinint
secu_string.hpp
this file contains the definition of secu_string class, a std::string like class but allocated in sec...
libdar::user_interaction::inherited_get_string
virtual std::string inherited_get_string(const std::string &message, bool echo)=0
method used to ask a question that needs an arbitrary answer.
libdar::user_interaction::printf
virtual void printf(const char *format,...)
libdar uses this call to format output before send to message() method.
libdar::user_interaction::inherited_message
virtual void inherited_message(const std::string &message)=0
libdar::secu_string
class secu_string
Definition: secu_string.hpp:58
libdar::user_interaction::inherited_get_secu_string
virtual secu_string inherited_get_secu_string(const std::string &message, bool echo)=0
same a get_string() but uses libdar::secu_string instead of std::string
libdar
libdar namespace encapsulate all libdar symbols
