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:

make cat_io_uring

if you see something unexpected:

make clean && make cat_io_uring

debug

• using default Address Sanitizer (ASan)
  append this on CFLAGS

  -fsanitize=address

• using valgrind

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

gdb ./cat_io_uring
> r something.txt
> bt

its will tell you where the program crash
