int sbumpc ( );

Get current character and increase get pointer

Returns the character currently pointed by the get pointer and advances it one position.

During its operation, the function will call the protected virtual member function uflow if the get pointer gptr points to the same position as the end pointer egptr before the call (or if it is a null pointer).

Notice that, although similar, the following functions have different behaviors:

• sgetc: returns the character pointed by the get pointer.
• sbumpc: advances the get pointer and returns the character pointed by it before the call.
• snextc: advances the get pointer and returns the character pointed by it after the call.

Parameters

Return Value

Example

// show file content - sbumpc () example
#include <iostream>
#include <fstream>
using namespace std;

int main () {

  char ch;
  streambuf * pbuf;
  ifstream istr ("test.txt");

  pbuf = istr.rdbuf();

  while (pbuf->sgetc()!=EOF)
  {
     ch = pbuf->sbumpc();
     cout << ch;
  }

  istr.close();

  return 0;
}

This example shows the content of a file on screen, using the combination of sgetc and sbumpc to read the input file.
