The purpose of libasm is to create a static library with classic libc functions, as strlen and strcpy. However, it stands out for being written exclusively in assembly code, more specifically the Intel x64 assembly code syntax. For instance, the static library libasm has the following available functions:
ft_strlen;ft_strcpy;ft_strcmp;ft_write;ft_read;ft_strdup;
As a bonus section of this project, the following functions were added, representing linked list data structure helping functions:
ft_list_push_front;ft_list_size;
The description of these functions may be found on your system under man 3 <function> (without ft_). As expected, the functions have to behave exactly like its C counterparts, including exceptions and errors.
The libasma.a library is compiled with nasm and make utilities, so be sure to have these packages installed on your system. A test file is available too, and you can use your favorite compiler to execute the tests. The following script may be helpful to setup a Debian based environment.
sudo apt update && sudo apt install build-essentials nasm
