// .NAME vtkBase64InputStream - Reads base64-encoded input from a stream.
// .SECTION Description
// vtkBase64InputStream implements base64 decoding with the
// vtkInputStream interface.
#ifndef vtkBase64InputStream_h
#define vtkBase64InputStream_h
#include "vtkIOCoreModule.h" // For export macro

// Description:
// Called after the stream position has been set by the caller, but
// before any Seek or Read calls. The stream position should not be
// adjusted by the caller until after an EndReading call.
void StartReading();
// Description:
// Seek to the given offset in the input data. Returns 1 for
// success, 0 for failure.

// Description:
// Read input data of the given length. Returns amount actually
// read.
size_t Read(void* data, size_t length);
// Description:
// Called after all desired calls to Seek and Read have been made.
// After this call, the caller is free to change the position of the
// stream. Additional reads should not be done until after another
// call to StartReading.
