clearerr

Usage

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

   ANSI


Description

   Clears error and EOF (end-of-file) flags associated with the stream fp.
   Once the error flag on a stream is set, any operation carried out on that
   stream will return an error status unless a call is made to clearerr.
   Note the EOF flag is cleared with each input from the stream.

Example 

   #include <stdio.h>
   #include <stdlib.h>

   int main()
   {
       FILE *stream;
       char *string = "Sample data";

       stream = fopen("file.dat","r");
       fprintf(stream,"%s\n",string);
       if(ferror(stream))

           {
               fprintf(stderr,"Write error to file.dat\n");
               clearerr(stream);
               fclose(stream);
               return EXIT_FAILURE;
           }
       printf("No error writing to file\n");
       fclose(stream);
       return EXIT_SUCCESS;
   }
