1. both of them return `0` on success, and `-1` on failure. 2. both of them set `errno` on failure. The differences are 1. `fileno` returns `int` type but `ftell` returns `long` type. 2. `ftell` will not affect the value of `error` on success, but this is not mentioned for `fileno`. https://github.com/llvm/llvm-project/pull/76207 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
