Clears the file error and EOF flags #include <stdio.h> void clearerr(FILE *fp); The clearerr( ) function is useful in handling errors in file I/O routines. It clears the end-of-file (EOF) and error flags associated with a specified FILE pointer. ExampleFILE *fp; int c; if ((fp = fopen("infile.dat", "r")) == NULL) fprintf(stderr, "Couldn't open input file.\n"); else { c = fgetc(fp); // fgetc( ) returns a character on success; if (c == EOF) // EOF means either an error or end-of-file. { if (feof(fp)) fprintf(stderr, "End of input file reached.\n"); else if (ferror(fp)) fprintf(stderr, "Error on reading from input file.\n"); clearerr(fp); // Same function clears both conditions. } else { /* ... */ } // Process the character that we read. } See Alsofeof( ), ferror( ), rewind( ) |
