Classes
class	Exiv2::LogMsg
	Class for a log message, used by the library. Applications can set the log level and provide a customer log message handler (callback function). More...
class	Exiv2::AnyError
	Error class interface. Allows the definition and use of a hierarchy of error classes which can all be handled in one catch block. Inherits from the standard exception base-class, to make life easier for library users (they have the option of catching most things via std::exception). More...
class	Exiv2::BasicError< charT >
	Simple error class used for exceptions. An output operator is provided to print errors to a stream. More...

Namespaces
namespace	Exiv2
	Provides classes and functions to encode and decode Exif and Iptc data. The libexiv2 API consists of the objects of this namespace.

Macros
#define	EXV_DEBUG   if (LogMsg::debug >= LogMsg::level() && LogMsg::handler()) LogMsg(LogMsg::debug).os()
	Shorthand to create a temp debug log message object and return its ostringstream.
#define	EXV_INFO   if (LogMsg::info >= LogMsg::level() && LogMsg::handler()) LogMsg(LogMsg::info).os()
	Shorthand for a temp info log message object and return its ostringstream.
#define	EXV_WARNING   if (LogMsg::warn >= LogMsg::level() && LogMsg::handler()) LogMsg(LogMsg::warn).os()
	Shorthand for a temp warning log message object and return its ostringstream.
#define	EXV_ERROR   if (LogMsg::error >= LogMsg::level() && LogMsg::handler()) LogMsg(LogMsg::error).os()
	Shorthand for a temp error log message object and return its ostringstream.

Typedefs
typedef BasicError< char >	Exiv2::Error
	Error class used for exceptions (std::string based)

Functions
