Functions

rewind bool rewind(IOHandle handle): Seek to beginning of the I/O stream.
seekAbsolute bool seekAbsolute(IOHandle handle, c_long offset): Seek to asolute position in the I/O stream. Useful because some function need to preserve it.
setupForFileIO void setupForFileIO(): Setup the IOStream for reading a file. The passed IOHandle will need to be a FILE*. For internal Gamut usage.
setupForMemoryIO void setupForMemoryIO(): Setup the IOStream for using a a file. The passed IOHandle will need to be a MemoryFile*. For internal Gamut usage.
setupSetupForLogging void setupSetupForLogging(IOStream io): Setup the IOStream for wrapping another IOStream and logging what happens. The passed IOHandle will need to be a WrappedIO. For internal Gamut usage.
skipBytes bool skipBytes(IOHandle handle, int nbytes): Skip bytes.
