## Namespaces
namespace | Exiv2
## Classes
class | Exiv2::BasicIo
| An interface for simple binary IO. More...
class | Exiv2::IoCloser
| Utility class that closes a BasicIo instance upon destruction. Meant to be used as a stack variable in functions that need to ensure BasicIo instances get closed. Useful when functions return errors from many locations. More...
class | Exiv2::FileIo
| Provides binary file IO by implementing the BasicIo interface. More...
class | Exiv2::MemIo
| Provides binary IO on blocks of memory by implementing the BasicIo interface. A copy-on-write implementation ensures that the data passed in is only copied when necessary, i.e., as soon as data is written to the MemIo. The original data is only used for reading. If writes are performed, the changed data can be retrieved using the read methods (since the data used in construction is never modified). More...
## Functions
DataBuf | Exiv2::readFile (const std::string &path)
| Read file path into a DataBuf, which is returned.
long | Exiv2::writeFile (const DataBuf &buf, const std::string &path)
| Write DataBuf buf to file path. Return the number of bytes written.
