CYIReadOnlyFILEBuffer Class Reference

Detailed Description

An implementation of std::streambuf backed by a YI_FILE handle. The wrapper uses YI_FREAD, YI_FSEEK and YI_FTELL, and only supports read operations.

Warning

This wrapper does not close the associated YI_FILE object when the wrapper is destroyed.
