std::resetiosflags(3)	       C++ Standard Libary	   std::resetiosflags(3)

NAME
     std::resetiosflags - std::resetiosflags

Synopsis
	Defined in header <iomanip>
	/*unspecified*/ resetiosflags( std::ios_base::fmtflags mask );

	When used in an expression out << resetiosflags(mask) or in >> resetios-
     flags(mask),
	clears	all  format  flags  of	the stream out or in as specified by the
     mask.

Parameters
	mask - bitmask of the flags to clear

Return value
	An object of unspecified type such that

	  * if out is an object of type std::basic_ostream<CharT,  Traits>,  the
     expression
	    out << resetiosflags(mask)
	       * has type std::basic_ostream<CharT, Traits>&
	       * has value out
	       * behaves as if it called f(out, mask)
	  *  if  in  is an object of type std::basic_istream<CharT, Traits>, the
     expression in
	    >> resetiosflags(mask)
	       * has type std::basic_istream<CharT, Traits>&
	       * has value in
	       * behaves as if it called f(in, mask)

	where the function f is defined as:

      void f(std::ios_base& str, std::ios_base::fmtflags mask)
      {
	  // reset specified flags
	  str.setf(ios_base::fmtflags(0), mask);
      }

Example
     // Run this code

      #include <iomanip>
      #include <iostream>
      #include <sstream>

      int main()
      {
	  std::istringstream in("10 010 10 010 10 010");
	  int n1, n2;

	  in >> std::oct >> n1 >> n2;
	  std::cout << "Parsing \"10 010\" with std::oct gives: " << n1 <<  '  '
     << n2 << '\n';

	  in >> std::dec >> n1 >> n2;
	  std::cout  <<  "Parsing \"10 010\" with std::dec gives: " << n1 << ' '
     << n2 << '\n';

	  in >> std::resetiosflags(std::ios_base::basefield) >> n1 >> n2;
	  std::cout << "Parsing \"10 010\" with autodetect gives: " << n1 << ' '
     << n2 << '\n';
      }

Output:
      Parsing "10 010" with std::oct gives: 8 8
      Parsing "10 010" with std::dec gives: 10 10
      Parsing "10 010" with autodetect gives: 10 8

	previously published C++ standards.

	  DR	 Applied to	       Behavior as published		 Correct
     behavior
	LWG 183 C++98	   resetiosflags could only be used  with	  usable
     with any
			   streams  of type std::ostream or std::istream charac-
