ios::clear

void clear( int nState = 0 );

Parameter

nState

If 0, all error bits are cleared; otherwise bits are set according to the following masks (ios enumerators) that can be combined using the bitwise OR ( | ) operator. The nState parameter must have one of the following values:

• ios::goodbit   No error condition (no bits set).
  
  
• ios::eofbit   End of file reached.
  
  
• ios::failbit   A possibly recoverable formatting or conversion error.
  
  
• ios::badbit   A severe I/O error.

Remarks

Sets or clears the error-state flags. The rdstate function can be used to read the current error state.
