clrerr -- Clear Error Flag and Return Status

SYNOPSIS

 #include <lcio.h>

 int clrerr(FILE *f);

DESCRIPTION

clrerr clears the error flag and end-of-file flag for the FILE object addressed by f.

RETURN VALUE

clrerr returns 0 if the error flag has been cleared or EOF if it could not be cleared. (The flag is not cleared if the operating system does not permit further use of the file or if the file is closed.)

EXAMPLE

  #include <lcio.h>

     /* Clear the error flag for a file. */
  int fixerr(FILE *f)
  {
        /* Show error flag cleared.      */
     if (clrerr(f) != 0){
        printf("Error on %s is permanent. Program aborted.n", fnm(f));
        abort();
     }
  return 0;
  }
