A file pointer is an opaque object that refers to a file. Opaque means that you should not attempt to delve into its specific value, other than to use it as a file pointer. FILE *fp; /* fp is the file pointer */ fp = fopen("somefile.txt"); if (fp == NULL) ...{exception}... fprintf(fp, "Hello somefile.txt"); fclose(fp);
