Synopsis:
    #include <stdio.h>
    void clearerr( FILE *fp );

Description:
    The clearerr function clears the end-of-file and error indicators for
    the stream pointed to by fp.  These indicators are cleared only when the
    file is opened or by an explicit call to the  clearerr or  rewind
    functions.

Returns:
    The clearerr function returns no value.

    feof, ferror, perror

Example:
    #include <stdio.h>

    void main()
      {
        FILE *fp;
        int c;

        c = 'J';
        fp = fopen( "file", "w" );
        if( fp != NULL ) {
          fputc( c, fp );
          if( ferror( fp ) ) {  /* if error        */
              clearerr( fp );   /* clear the error */
              fputc( c, fp );   /* and retry it    */
          }
        }
      }
