introduction
-
this repository is a clone of the cat *nix command but made it myself.
used to know how io_uring works, and some posix function

compile instruction:
```sh
make cat_io_uring
```

if you see something unexpected:
```sh
make clean && make cat_io_uring
```

debug
-
- using default Address Sanitizer (ASan)

append this on CFLAGS
```sh
-fsanitize=address
```

- using valgrind
```sh
valgrind --leak-check=full \
--show-leak-kinds=all \
--track-origins=yes \
--verbose \
./cat_io_uring something.txt
```

- gdb
if you found something crash, run program with gdb, example

```sh
gdb ./cat_io_uring
> r something.txt
> bt
```
its will tell you where the program crash
