Get current character.
  Returns the character at current get position, or EOF (traits::eof) if the current get pointer is at the end of the input sequence.
  As a virtual function it can be overriden in derived classes in order to return an element directly from an external source of characters associated with the streambuf-derived object and to set new values for gptr and egptr pointers.

Parameters.

none

 

Return Value.
  The character available at the get position.
  EOF if the get pointer is at the end of the input sequence.

Basic template member declaration ( basic_streambuf<charT,traits> ):
