streambuf::sbumpc

Usage

   #include <iostream.hpp>
   int streambuf::sbumpc();

Description

   The sbumpc function returns the value of the character at the get
   pointer, then moves the get pointer along one. If the get pointer is
   already beyond the end of the get area, the underflow function will be
   called to attempt to replenish the get area. If this fails to do so,
   sbumpc returns EOF.

Example 

   streambuf sb;
   ...;
   // stream is "abcdefg", get pointer on 'a'

   int c = sb.sgetc();
   cout << char(c);    // output 'a'
   c = sb.sbumpc();

   cout << char(c);    // output 'a'
   c = sb.sgetc();
   cout << char(c);    // output 'b'

Return Value

   An int that will be EOF if some error occurs, or there are no more
   characters to be had, or otherwise a positive int representing the
   character (treating the character as unsigned char).
