clearerr()               Clear Error Indicator for a Stream

 #include <stdio.h>

 void       clearerr(stream);
 FILE       *stream;                     Pointer to file structure

    clearerr() sets the stream's error and end-of-file indicators to 0.

    Returns:    There is no return value.

      Notes:    Once set, a stream's indicators are not automatically
                cleared by subsequent operations; operations to the
                stream will continue to return an error until either
                clearerr() or rewind() is called, or the stream is
                closed.

  -------------------------------- Example ---------------------------------

    The following statements open a file, get characters from the file,
    report an error, then clear the indicators (if necessary) and close
    the file.

         #include <stdio.h>

         FILE *stream;
         int c;

         main()
         {
              If ((stream = fopen("new.txt","r+"))!= NULL) {
                 while (!feof(stream)){
                       c = getc(stream);
                       if (ferror(stream) {
                          printf("write error\n");
                          clearerr(stream);
                      }
                  }
                  fclose(stream);
          }
